Question

You are assigned 32 math exercises for homework. You do 87.5% before dinner, how many more problems do u have let to do after dinner.

Answer 1

32 assignments, 87.5% done. That leaves 12.5% to finish (100 - 87.5). Next, you convert 12.5% into a decimal: 0.125
After that, multiply 32 by 0.125 to get 12.5%, which is 4, the remaining amount of assignments. You have 4 assignments left.

Answer 2

You have to do 4 homework assignments after dinner:)
