Simplify the ratio. 45 minutes to 1 hour
1 hour can be simplified to 60 minutes because there are 60 minutes in one hour
thus, the ratio becomes 45:60
if we want to simplify that even more, we have to divide both numbers by 5
45/5 = 960/5 = 12
therefore, the ratio becomes 9:12
H=hours M=minutesYou convert 1 hour into 60 minutesSo your ratio would be 60:45Then you find the common denominator, which the highest is 15Divide by both45÷15=360÷15=4Therefore, your ratio would be 3:4
