When both the measures are in the same units, then the ratio can be calculated. 1 hour = 60 minutes ⇒ 2 hours = 2 x 60 minutes = 120 minutes The ratio of 50 minutes to 2 hours is then: 50 : 120 ⇒ 5 : 12
50 minutes:2 hrs =50 minutes:120 minutes =5:12 [dividing both by 10]
The ratio of 50 minutes to 1 1/2 hours is 5:9. Once the units are the same they can be cancelled out and the numbers reduced by any common factor until their highest common factor is 1. 1 hours = 60 mins → 1½ hours = 1½ × 60 mins = 90 mins Therefore the ratio is: 50 mins : 1½ hours = 50 mins : 90 mins = 50 : 90 = 5 : 9
It is 7/30.
45 minutes to 2 hours is the same as 45 minutes to 120 minutes. This can be reduced to 9/24, or 9 to 24.
