# 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.

## Example 1

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)

## Example 2

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)

Now try this question:

Question

Round $$103.4$$ to the nearest ten.

$$103.4$$ lies between $$100$$ and $$110$$

$$103.4$$ is nearer to $$100$$ than $$110$$

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