One hour is 60 minutes.
A quarter of an hour is 60 minutes/4 = 60/4 minutes = 15 minutes.
Three quarters of an hour = 3*a quarter of an hour = 3*15 minutes = 45 minutes.

No, 1 quarter of a hour is 15 minutes, so 3 quarters of a hour is 45 minutes. In quarters, an your goes 15, 30, 45, 60.
I believe there is an hour and 45 minutes because 75 means 3 quarters from a 100% and 45 means also 3 quarters from 60 (which are the minutes from an hour) .and therefore...1.75 hours equals an hour and 45 minutes
3/4 (said as three quarters) of a minute is 45 seconds, so 3 and 3 quarters of in minutes is 3 minutes and 45 seconds
(60 × 4) + 45 = 285 minutes Method: There are 60 minutes in 1 hour: 60 minutes x 4 hours equals 240 minutes. There are 45 minutes in 3 quarters of 1 hour. Therefore, add 240 and 45 which equals 285 minutes.
45 minutes is 3/4 of an hour. 45/60 = 3/4
