1:3
9:27 to 9:30 = 3 minutes9:30 to 11:00 = 90 minutes 11:00 to 11:15 = 15 minutes TOTAL minutes = 3 + 90 + 15 = 108 minutes
The ratio of 90 to 18 is written as 90/18
36 minutes/(11 min 36 sec) = 2160 sec/696 sec = 90/29 which cannot be simplified further.
27:9 . '9' is a common factor , so divide by '9' Hence 3:1 Mathemetically it is written as 27:9 :: 3:1 NB Note the use of 'colons'.
90 seconds = 1.5 minutes. So the ratio is 1.5 : 3 or 1:2
1:3
90/70 or 9/7
5/9
Oh, dude, so like, the ratio of 90 seconds to 7 minutes is 1:4. It's like, you just gotta convert the minutes to seconds to make the math work, but who really cares about ratios anyway, am I right? Like, just set a timer and enjoy the show, man.
90 min/8 hours = 90 min/480 min = 3/16
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
9:27 to 9:30 = 3 minutes9:30 to 11:00 = 90 minutes 11:00 to 11:15 = 15 minutes TOTAL minutes = 3 + 90 + 15 = 108 minutes
The ratio of 90 to 18 is written as 90/18
36 minutes/(11 min 36 sec) = 2160 sec/696 sec = 90/29 which cannot be simplified further.
