14 out of 20 students pack their lunches. what percent of students pack their lunches?

1 answer:

7 0

Think of it as a fraction (14/20). If you multiply 20 by 5, you get 100. Whatever you do to the bottom, you have to do to the top. So 14 x 5 would be 70. The entire fraction would be 70/100 or 70%.
