Rounding to the nearest whole number

In many calculations you will be expected to round off your answer to the nearest whole number or to the nearest ten.

Examples

Write 38.7 to the nearest whole number

 

38.7 lies between 38 and 39

38.7 is nearer to 39 than 38

So, 38.7 = 39 (to the nearest whole number)

A horizontal line with 38 at the left end, 39 at the right end, 38.5 in the centre and 38.7 marked with an orange dot.

Write 6.5 to the nearest whole number

 

6.5 lies between 6 and 7

6.5 lies mid-way between 6 and 7

When this happens always round up

So, 6.5 = 7 (to the nearest whole number)

A horizontal line with the number 6 at the left end, 7 at the right end, and 6.5 in the middle.

Now try this one:

Question

Round 103.4 to the nearest ten

toggle answer

Answer

103.4 lies between 100 and 110

103.4 is nearer to 100 than 110

So, 103.4 = 100 (to the nearest ten).

Horizontal line with 100 at the left end, 110 at the right end, 105 in the middle and 103.4 marked with an orange dot.
