30 minutes is 1/6th of 3 hours, so the ratio of 30 minutes to 3 hours is 1:6
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
The ratio is 60 minutes :1 hour.
The ratio works out as 7 to 60
Just convert the 2 hours to minutes. Then you have the ratio:24 minutes : (the equivalent of 2 hours) Which, if you wish, you can then simplify.
Minutes : Hour = 60 : 1
In minutes it is: 7 to 36
