You can put this solution on YOUR website! If you answered 80% of the questions on a math examination correctly and the number of your correct questions was 112, then how many total questions were on the exam?
Let x = total questions on the exam
the equation, change 80% to .80
.80x = 112
solve, divide both sides by .8
x = 112/.8
x = 140 questions on the exam
:
"Out of 140 questions, you got 112 right, which is 80% of 140"
