Change Times Given in Decimals into Hours and Minutes

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
