There are 60 minutes in one hour.

To change decimal fractions of hours to minutes, we multiply the decimal part by 60.

Example

4.2 hrs is 4 hrs and 0.2 hrs.

Change 0.2 hrs to minutes by multiplying by 60.

0.2 hrs = 0.2 × 60 = 12 minutes.

4.2 hrs = 4 hrs 12 minutes

Does that make sense?

Let's try some questions together now.
