RBSE Solutions Class 5 Maths Chapter 1 Numbers More Ques

 

Question 1. Let's play a game to make numbers. In this game numbers are displayed as symbols. Each symbol stands for a place value: One (ones place), a different symbol for Ten (tens place), another for One Hundred (hundreds place), one for One thousand (thousands place), and another for Ten thousand (ten thousands place). With the help of this symbolic picture, the numbers are written like this:
(i) One (hundreds symbol) and One (tens symbol) = \( 100 + 10 = 110 \)
(ii) One (thousands symbol), three (hundreds symbol) and four (ones symbol) = \( 1000 + 300 + 4 = 1304 \)
(iii) Five (ten thousands symbol), six (hundreds symbol) and two (ones symbol) = \( 50000 + 60 + 2 = 50062 \)
Now, fill in the blanks:
(iv) Two (thousands symbol), five (hundreds symbol), three (tens symbol) and seven (ones symbol) = ..... + ..... + ..... = 2537
(v) Four (ten thousands symbol), two (thousands symbol) and one (ones symbol) = ..... + ..... + ..... = .....
Answer: We need to fill in the missing expanded form and the final number based on the given symbols and their place values. Each symbol represents a specific value, which helps us build the complete number.
(iv) Two (thousands symbol), five (hundreds symbol), three (tens symbol) and seven (ones symbol) = \( 2000 + 500 + 30 + 7 = 2537 \)
(v) Four (ten thousands symbol), two (thousands symbol) and one (ones symbol) = \( 40000 + 2000 + 1 = 42001 \)
In simple words: Each symbol shows a number's place value. We add up the values from each symbol to get the total number. We just filled in the missing numbers based on these rules.

🎯 Exam Tip: Always pay attention to what each symbol represents (ones, tens, hundreds, thousands, ten thousands) to correctly form the number.

 

Question 2. Make a small circle within the given circle and write the number in table using symbols that fall within the small circle.
Answer: We count the symbols representing each place value within the small circle and then write the number in expanded form and standard form in the table. Understanding place values helps us quickly identify the value of each digit.

In simple words: We looked at each small circle to see how many symbols were there for ten thousand, thousand, hundred, tens, and ones. Then, we wrote these counts in the table, showed their expanded sum, and finally the full number.

🎯 Exam Tip: When filling tables, carefully count the number of symbols for each place value to avoid errors in the expanded and final number forms.

 

Question 3. (i) Write in words and expanded form of 5-digit numbers which are formed from 8, 5, 2, 4 and 0.
(ii) Can you make the greatest and smallest 5-digit number using the given digits?
Answer:
(i) We can form several 5-digit numbers using the digits 8, 5, 2, 4, and 0. Below are some examples with their expanded forms and names in words. Understanding place value helps in writing numbers in expanded form.

(ii) Yes, we can make the greatest and smallest 5-digit numbers using these digits (8, 5, 2, 4, and 0). To make the greatest number, arrange the digits from largest to smallest. To make the smallest, arrange them from smallest to largest, but avoid starting with zero for the first digit of a 5-digit number.
Greatest five-digit number: \( 85420 \)
Smallest five-digit number: \( 20458 \)
In simple words: For part (i), we wrote some numbers using the given digits, showing them spread out and in words. For part (ii), yes, we can make the biggest and smallest numbers by carefully putting the digits in order.

🎯 Exam Tip: When forming the smallest number, remember that a zero cannot be the first digit for a number of a specific length (e.g., a 5-digit number cannot start with 0).

 

Question 4. Find out the place value of 9 and 6 in number 59264?
Answer: In the number 59264, we need to find the value that each digit holds based on its position. The place value tells us how much each digit is worth. In \( 59264 \), the digit 9 is in the thousands place, and the digit 6 is in the tens place.
Place value of 9 = \( 9 \times 1000 = 9000 \)
Place value of 6 = \( 6 \times 10 = 60 \)
In simple words: For the number 59264, the 9 means nine thousands (9000), and the 6 means six tens (60).

🎯 Exam Tip: To find the place value of a digit, multiply the digit by the value of its position (ones, tens, hundreds, thousands, etc.).
