Sometimes measurements, money and times are given in decimal format, which is not always very convenient or easy to understand.

Sometimes, when using a calculator to find an answer, it is necessary to interpret your answer sensibly.

For example, if the answer is in money, then 4.7 means **£4.70**.

If the answer is in kilometers, then 12.09 means **12 km 90 m**.

However, If the answer is in hours, the decimal part must be changed into minutes by **multiplying it by 60**.

**Examples**

8.15 hours is 8 hours and 0.15 hours

0.15 × 60 = 9 minutes

So **8.15 hours = 8 hours 9 minutes**

5.24 hours is 5 hours and 0.24 hours

0.24 × 60 = 14.4 minutes.

So** 5.24 hours is 5 hours 14.4 minutes**
