## Rounding off numbers worksheets - Solution

1)  Consider multiples of 10 before and after 521. ( i.e. 520 and 530 )

We find that 521 is nearer to 520 than to 530.

It has been illustrated in the picture given below.

Therefore, the nearest tens of 521 is 520.

2)  Consider multiples of 100 before and after 521. ( i.e. 500 and 600 )

We find that 521 is nearer to 500 than to 600. So, the nearest hundreds of 521 is 500.

3) The nearest tens = 47,620

4)  The nearest hundreds = 47,600

5)  The nearest thousands = 48,000

6)  The nearest ten thousands = 50,000

7)  It is 36.73 round to two decimal places. (Since the last digit 9 > 5, we add 1 to 2 and make it 3).

Therefore, 36.729 ≃ 36.73 (Round to two decimal place)

8)  Look at the second decimal in 36.729, Here it is 2 which is less than 5, so we leave 7 as it is.

Therefore, 36.729 ≃ 36.7 (Round to one decimal place)

9)  It’s approximation is 36.75, round to two decimal places. Since the last digit is 5, we add 1 to 4 and make it 5.

10)  It’s approximation is 36.7, round to one decimal place. Since the second decimal is 4, which is less than 5, we leave 7 as it is.

36.745 ≃ 36.7

11)  Rounded to one decimal place is 2.1

12)  Rounded to two decimal places is 2.15

13)  Rounded to three decimal places is 2.148

14)  Rounded to four decimal places is 2.1483

15)  288

16)  3998

17)  4857

18)  5000

19)  2

20)  1
