Addition of Whole Numbers Worksheet
In Addition of Whole Numbers Worksheet you will get different types of problems on properties of addition of whole numbers, representation of whole numbers on a number line and word problems on addition of whole numbers.
1. Find the sum of the whole numbers 512, 791 and 488.
Solution:
512 + 791 + 488
= (512 + 488) + 791. [Rearranging the numbers in suitable order]
= 1000+791
= 1791.
2. Add by grouping suitably:
(i) 303, 262, 197 and 238
(ii) 425, 712 and 0.
Solution:
(i) 303 + 262 + 197 + 238
= (303 + 197) + (262 + 238)
= 500 + 500
= 1000.
(ii) 425 + 712 + 0
= 425 + 712
= 1137.
3. Write all the whole numbers in the ascending order which lie between 96 and 118.
Solution:
All whole numbers in the ascending order which lie between 96 and 118 are 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117.
4. With the help of a number line, compare whole numbers 8 and 15.
Solution: Draw a number line and show the given numbers by a dot as shown below:
As 8 is to the left of 15, or 15 is to the right of 8, so 15 is greater than 8, or 8 is less than 15.
5. Write five consecutive whole numbers beginning from 8700198.
Solution:
Five consecutive whole numbers beginning from 8700198 are 8700198, 8700199, 8700200 and 8700201.

4. Show that 4 < 7 with the help of a number line.
5. Write four consecutive whole numbers beginning from 456098.
6. Fill in the blanks to get true statements:
(i) 785 + 48 = _____ + 785
(ii) 384 + 24 + 762 = 24 + (_____ + 384).
