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 = 9
60/5 = 12
therefore, the ratio becomes 9:12
H=hours M=minutes You convert 1 hour into 60 minutes So your ratio would be 60:45 Then you find the common denominator, which the highest is 15 Divide by both 45÷15=3 60÷15=4 Therefore, your ratio would be 3:4
