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

90 sec to 7min
90 min/8 hours = 90 min/480 min = 3/16
Well, honey, if you wanna get technical, 50 minutes to one and a half hours is a ratio of 5:9. You could also simplify that to 10:18 if you wanna be fancy. But who's got time for all that math? Just set a timer and enjoy a nice cup of tea while you wait.
