Answer 1

`62 (3)/(4)*60=62*60+ (3)/(4)*60= 3720 + 3*15=3720+45=\boxed{3765} \\ \\ 870 \ minutes= (870)/(60)= (87)/(6)=14 (3)/(6)=\boxed{ 14(1)/(2) } \ hours \\\\225 \ minutes= (225)/(60)= (15)/(4)=\boxed{ 3(3)/(4) } \ hours \\\\75 \ minutes= (75)/(60)= (5)/(4)=\boxed{ 1(1)/(4) } \ hours \\\\720 \ minutes= (720)/(60)= (72)/(6)=\boxed{ 12 } \ hours`

Answer 2

Divide the minutes by 60 to get the number of hours. For example 870/60 gives 14 1/2 hours. 225/60 is 3 3.4 hours.
