Question I. Using the digits given in the petals of each flower, write the smallest and the greatest number and circle the even number.


Smallest number: A ____________ B _____________ C___________
Greatest number : A ____________ B _____________C___________
Answer:
Smallest number:
- A: 4579
- B: 2038 (Even)
- C: 1568 (Even)

Greatest number:
- A: 9754 (Even)
- B: 8320 (Even)
- C: 8651
In simple words: To make the smallest number, put the digits from smallest to largest. To make the greatest number, put them from largest to smallest. Even numbers are those that end with 0, 2, 4, 6, or 8.

Exam Tip: Remember that a 4-digit number cannot start with 0. If you have a 0, use the next smallest digit first, then place the 0 in the second position.

Question II. Multiply
a. 218 X 12
b. 368 X 7
Answer:
a. \( 218 \times 12 = 2616 \)
Working:
\( \begin{array}{r@{\quad}l} &\phantom{0}218 \\ \times &\phantom{00}12 \\ \hline &\phantom{0}436 \quad (218 \times 2) \\ +&2180 \quad (218 \times 10) \\ \hline &2616 \end{array} \)

b. \( 368 \times 7 = 2576 \)
Working:
\( \begin{array}{r@{\quad}l} &\phantom{0}368 \\ \times &\phantom{000}7 \\ \hline &2576 \end{array} \)
In simple words: Multiply the numbers to find the total product. Double-digit multiplication is done by multiplying step-by-step and then adding the results together.

Exam Tip: When multiplying by a two-digit number, remember to write a placeholder zero in the ones place of the second row of working.

Question III. Round off the cost of each item to the nearest 10
Items in the shopping cart:
- Rs. 16
- Rs. 89
- Rs. 76
- Rs. 43
- Rs. 56
- Rs. 68

Answer:
- Rs. 16 rounds off to Rs. 20
- Rs. 89 rounds off to Rs. 90
- Rs. 76 rounds off to Rs. 80
- Rs. 43 rounds off to Rs. 40
- Rs. 56 rounds off to Rs. 60
- Rs. 68 rounds off to Rs. 70
In simple words: Look at the last digit of each price. If it is 5 or more, round up to the next ten. If it is 4 or less, round down to the nearest ten.

Exam Tip: Always look at the ones digit first when rounding to the nearest ten. Numbers ending in 5, 6, 7, 8, or 9 always round up.

Question IV. Divide
a. 546÷7= _______, Dividend = _________, Divisor = __________
    Quotient = __________ Remainder = _________
b. 689÷ 4= _______ Dividend = _________, Divisor = __________
    Quotient = __________ Remainder = _________
Answer:
a. \( 546 \div 7 = 78 \)
- Dividend = 546
- Divisor = 7
- Quotient = 78
- Remainder = 0

b. \( 689 \div 4 = 172 \) remainder 1
- Dividend = 689
- Divisor = 4
- Quotient = 172
- Remainder = 1
In simple words: Dividing splits a number into equal parts. The dividend is the number being split, the divisor does the splitting, the quotient is the answer, and any leftover part is the remainder.

Exam Tip: Check your division answers by multiplying the quotient by the divisor and adding the remainder to see if you get back the dividend.

Question V. solve
1. 72 X 1 = _________
2. 53X 0 =_________
3. 78 ÷ 78 = ________
4. 0 ÷ 19 = __________
5. 65 ÷ 1 = __________
6. 9 X 200 = ___________
7. 8 X 7 = __________
8. 16 X 1000 = ______________
Answer:
1. 72 x 1 = 72
2. 53 x 0 = 0
3. 78 ÷ 78 = 1
4. 0 ÷ 19 = 0
5. 65 ÷ 1 = 65
6. 9 x 200 = 1800
7. 8 x 7 = 56
8. 16 x 1000 = 16000
In simple words: Remember these rules: any number times 1 is itself, any number times 0 is 0, any number divided by itself is 1, and 0 divided by any number is 0.

Exam Tip: For multiplication by multiples of 10, 100, or 1000, simply multiply the non-zero digits and append the correct number of zeros at the end.
