In simple words: Commas help us read large numbers easily by grouping digits into periods.
Exam Tip: Remember that Indian periods group as thousands (2 digits), lakhs (2 digits), and crores (2 digits), whereas International periods group in sets of 3 digits (thousands, millions, billions).

Question 2. Give the place, place value and face value of the underlined numbers :
Number
65789002
309.008
298.603
Answer:

In simple words: Face value is the digit itself, while place value depends on the position of the digit in the number.
Exam Tip: For decimals, places to the right of the decimal point are tenths, hundredths, thousandths, and their place values are fractions or decimals.

Question 3. Write the expanded form for the following:
a. 75680912
b. 2368.912
Answer: a. 75680912 = \(70,000,000 + 5,000,000 + 600,000 + 80,000 + 0 + 900 + 10 + 2\)
b. 2368.912 = \(2000 + 300 + 60 + 8 + 0.9 + 0.01 + 0.002\) (or using fractions: \(2000 + 300 + 60 + 8 + \frac{9}{10} + \frac{1}{100} + \frac{2}{1000}\))
In simple words: Expanded form breaks down a number into the sum of the place values of each digit.

Exam Tip: Do not forget to include decimal fractions when expanding numbers containing decimal parts.

Question 4. Write the standard form for the following
a. 80000 + 5000 + 7 + \(\frac{2}{10}\) + \(\frac{9}{100}\) + \(\frac{3}{1000}\)
Answer: \(80000 + 5000 + 0 + 7 + 0.2 + 0.09 + 0.003 = 85007.293\)
In simple words: Combine all the whole number parts and decimal parts together into a single number.

Exam Tip: Watch out for missing place values (like hundreds and tens in this problem) and put a 0 in their place.

Question 5. Write the predecessor and successor for the following:
a. 2345678
b. 3867.21
Answer: a. For 2345678:
- Predecessor = \(2345678 - 1 = 2345677\)
- Successor = \(2345678 + 1 = 2345679\)

b. For 3867.21 (assuming whole number predecessor/successor or decimal step of 1):
- Predecessor = \(3867.21 - 1 = 3866.21\) (or 3867 if referring to whole numbers)
- Successor = \(3867.21 + 1 = 3868.21\) (or 3868 if referring to whole numbers)
In simple words: Predecessor is 1 less than the number, and successor is 1 more than the number.

Exam Tip: For standard school problems, predecessor and successor usually refer to subtracting and adding 1.

Question 6. Complete the table by rounding off the chosen numbers to the indicated place value.
Answer:

In simple words: Look at the digit to the right of the target place; if it is 5 or more, round up, otherwise round down.
Exam Tip: Always check the immediate digit to the right of the place value you are rounding to.

Question 7. Using the given digits, form the greatest and smallest numbers possible without repetition
a. 8, 0, 4, 7, 2
Answer: - Greatest number: 87420
- Smallest number: 20478 (since 0 cannot be at the ten-thousands place)
In simple words: Arrange digits in descending order for the greatest number, and ascending order for the smallest number.

Exam Tip: Never start a number with 0 unless instructed otherwise; place the next smallest non-zero digit first.

Question 8. Using the given digits, form the greatest and smallest 7 digit numbers possible with repetition
a. 1, 0, 9, 8
Answer: - Greatest 7-digit number: 9999981
- Smallest 7-digit number: 1000009
In simple words: Repeat the largest digit to form the greatest number, and repeat 0 after the smallest non-zero digit to form the smallest number.

Exam Tip: When repetition is allowed, reuse the extreme digits (9 for greatest, 0 or 1 for smallest) to fill all 7 places.

Question 9.
a. Round 507.890 to the nearest hundredth
b. Round 12.580 to the nearest tenth
c. Round 46.89 to the nearest whole number
Answer: a. Nearest hundredth of 507.890 = 507.89
b. Nearest tenth of 12.580 = 12.6
c. Nearest whole number of 46.89 = 47
In simple words: Identify the target decimal place and check the digit to its right to decide whether to round up or keep the same.

Question 1. Fill in the blanks with either >, <, or = sign.
a. 812,206 ________ 8,12,206
b. 2.22 ______ 2.01
c. 3108.23 _____ 56.009
d. 7,98,967 ______ 798.967
Answer: a. 812,206 = 8,12,206
b. 2.22 > 2.01
c. 3108.23 > 56.009
d. 7,98,967 = 798,967
In simple words: Compare numbers place by place from left to right to find which is greater.

Exam Tip: Commas in Indian numbering (like 8,12,206) and standard numbering (812,206) can represent the exact same value.

Question 2. Circle the biggest number and underline the smallest:
a. 8636.777   863.677   86.3777   8637
b. 1,56,789   23,482,678   89,10,234   4,456,678
Answer: a. Biggest: 8637, Smallest: 86.3777
b. Biggest: 23,482,678, Smallest: 1,56,789
In simple words: Compare the whole number parts first; larger whole numbers mean larger values.

Exam Tip: Count the digits first when comparing large whole numbers; more digits mean a larger number.

Question 3. Arrange in ascending order:
a. 78.09, 2.005, 56.235, 3.102
Answer: Ascending order (smallest to greatest):
2.005, 3.102, 56.235, 78.09
In simple words: Ascending means going up from the smallest value to the largest value.

Exam Tip: Align decimal points mentally and compare digits from left to right.

Question 4. Arrange in descending order:
a. 24,123,456, 24,12,345, 2,42,345, 2,41235
Answer: First, normalize the numbers to a common format:
- 24,123,456 = 2,41,23,456
- 24,12,345 = 24,12,345
- 2,42,345 = 2,42,345
- 2,41,235 = 2,41,235
Descending order (greatest to smallest):
24,123,456, 24,12,345, 2,42,345, 2,41,235
In simple words: Descending means going down from the largest value to the smallest value.

Exam Tip: Convert international commas to Indian commas or vice versa to avoid confusion before comparing.

For Subtraction Puzzle:
7590860 - 438732 = 7152128 (Resolving grid to match given result 325446: 7990860 - 7665414 = 325446, or standard worksheet solution: missing digits filled to make the vertical operation correct).
In simple words: Work backwards using basic addition and subtraction rules to find the missing digits.

Exam Tip: Check carries and borrows carefully when solving vertical arithmetic puzzles.

WORD PROBLEMS - ALL OPERATIONS

Question 1. The NIE newspaper printed 64,809 copies in a day. Of these copies 645 were distributed to TGES. How many copies were distributed to other schools?
Answer: Total copies printed = 64,809
Copies distributed to TGES = 645
Copies distributed to other schools = \(64,809 - 645 = 64,164\)
In simple words: Subtract the copies given to TGES from the total copies printed.

Exam Tip: State each sentence clearly before writing the final subtraction equation.

Question 2. Grade 5 went on an adventure trip. They travelled the first 500km by bus and the next 34,600 km by train to reach their destination. What distance did they cover?
Answer: Distance travelled by bus = 500 km
Distance travelled by train = 34,600 km
Total distance covered = \(500 + 34,600 = 35,100\text{ km}\)
In simple words: Add the distance travelled by bus and train together.

Exam Tip: Always include units (km) in your final answer statement.

Question 3. A business man built a big house. He bought a plot of land for Rs. 70 lakhs. He spent Rs. 30,23,490 for the construction and Rs. 4,34,509 for the interior decoration. How much money did he spend for his house?
Answer: Cost of plot = Rs. 70,00,000
Cost of construction = Rs. 30,23,490
Cost of interior decoration = Rs. 4,34,509
Total money spent = \(70,00,000 + 30,23,490 + 4,34,509 = 1,04,57,999\)
Total money spent = Rs. 1,04,57,999 (One crore four lakh fifty-seven thousand nine hundred ninety-nine)
In simple words: Add the cost of the land, construction, and interior decoration to find the total expense.

Question 4. 2340 TV sets are manufactured daily by Sony Corporation. Find the total number of sets manufactured in January 2004 and February 2004.
Answer: TV sets manufactured daily = 2340
Days in January 2004 = 31 days
Days in February 2004 = 29 days (2004 was a leap year)
Total days = \(31 + 29 = 60\text{ days}\)
Total TV sets manufactured = \(2340 \times 60 = 1,40,400\)
In simple words: Multiply the daily production by the total number of days in both months combined.

Exam Tip: Remember that 2004 is divisible by 4, so it is a leap year with 29 days in February.

Question 5. The Himalaya Book Store sells 2389 books every day. Find out how many books the store would have sold last month.
Answer: Assuming "last month" refers to a standard 30-day month (or specify standard month of 30 days):
Books sold per day = 2389
Number of days in the month = 30
Total books sold = \(2389 \times 30 = 71,670\)
In simple words: Multiply daily sales by 30 days.

Exam Tip: State your assumption if the month is taken as 30 days or specify the exact month.

Question 6. What is the difference between the greatest 5-digit number and smallest 6-digit number?
Answer: Greatest 5-digit number = 99,999
Smallest 6-digit number = 1,00,000
Difference = \(1,00,000 - 99,999 = 1\)
In simple words: Subtract the greatest 5-digit number from the smallest 6-digit number.

Question 7. The total production of 16,395 tons of rice was divided equally and sent to 76 ration shops and the remaining was used for mid-day meals for students of the government school on Republic Day. Find the quantity of rice used for mid-day meals.
Answer: Total rice production = 16,395 tons
Number of ration shops = 76
\(16,395 \div 76 = 215\) tons per ration shop with a remainder of 55 tons.
Quantity of rice sent to ration shops = \(76 \times 215 = 16,340\text{ tons}\)
Remaining rice used for mid-day meals = \(16,395 - 16,340 = 55\text{ tons}\)
In simple words: Divide the total rice by the number of shops; the remainder is the rice left for mid-day meals.

Exam Tip: The remainder of a division problem represents the leftover quantity.

Question 8. In our school library there are 14,567 story books, 8,450 moral value books and 260 activity books? How many books are there in our library?
Answer: Number of story books = 14,567
Number of moral value books = 8,450
Number of activity books = 260
Total number of books = \(14,567 + 8,450 + 260 = 23,277\)
In simple words: Add all types of books together to find the total library collection.
