#### Worksheet Overview

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 kilometres, then 12.09 means 12 km 90 m. (0.9 has been multiplied by 1,000 because there are 1,000 metres in a kilometre)

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

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
