Question

It took Jane 1 hour and 20 minutes to do her math homework while it took Ava just 45 minutes. Find the ratio of time it took Jane to do her homework to the time it took Ava to do hers.

Answer 1

9:16

Explanation:

so the ratio is 1hr 20min to 45 min which is the same as saying 80 min(because an hour is 60 min) to 45 min. now we simplify both by 5 to get 9:16
