You would set this up as Part÷Whole=Percent÷100
Part=117
Whole= X
Percent=78
117÷X=78÷100
Set these up as fractions and cross multiply. You will get 117×100=78X
117×100=11,700
Divide both sides by 78 and you get x=150
There were 150 problems
To answer this all you need to do is divide 120 by 50
120/50
2.4
So it will take 2 hours and 24 minutes (.4 of 60 to get the 24)
