Question

You are assigned 32 math questions for homework. You complete 87.5% of these before dinner. How many questions do you have left to do after dinner?

Answer 1

4 questions should be left

Answer 2

4 questions

Explanation:

To find a percentage of a number, you move the decimal mark all the way to the left.

87.5% becomes 0.875

Next you multiply 32 by 0.875 to find the percentage of questions that are completed

32 x 0.875 = 28

28 out of 32 questions have been solved, so now you subtract 28 from 32

32 - 28= 4
