What do you think you should do with those two numbers?
What is the best way to figure out the answer?

do units so the ones you do not want cancel
Here I used 1 hr/0 min so min cancelled
If I had hours and wanted minutes I would multiply by
( 60 min/1 hour )
This is easy when you only have one conversion but when you get to Chemistry and other science you have to do a lot of them at once and the canceling thing is important.

60 min IS 1 hour
so 60 min/1 hour is the same numerator and denominator
