Question

what is 1/5 of an hour

Answer 1

there are 60 minutes in 1 hour, so 1/5 is one in every five. You can also just multiply 60 by 1/5:
$\frac{60}{1} * \frac{1}{5} =12$
so there are 12 minutes in 1/5 of an hour.

Answer 2

12 minutes this is because 60/5 = 12 or you can check it by doing 12×5 which is 60
