## How to Convert Hours to Minutes

*Example: How many minutes are equivalent to 64.51 hours?*

As;

1 hours = 60 minutes

64.51 hours = Y minutes

Assuming Y is the answer, and by criss-cross principle;

Y equals 64.51 times 60 over 1

(i.e.) Y = 64.51 * 60 / 1 = 3870.6 minutes

Answer is: 3870.6 minutes are equivalent to 64.51 hours.
