We are required to simplify the ratio 3 hours 1 hour 20 minutes

The simplest ratio of 3 hours : 1 hour : 20 minutes is 9 : 3 : 1

Convert hour to minutes

1 hour = 60 minutes

3 hours = 60 minutes × 3

= 180 minutes

1 hour = 60 minutes

So,

3 hours : 1 hour : 20 minutes

= 180 minutes : 60 minutes : 20 minutes

= 18 : 6 : 2

= 9 : 3 : 1

Therefore, the simplest ratio of 3 hours : 1 hour : 20 minutes is 9 : 3 : 1
