There are 500 children in elementary.Today 25 children are away.what percentage are present?

1 answer:

4 0

This can be solved using a proportion

100 : 500 = x : 475
100 percent is 500, x percent is based on the remaining 475 students
100 x 475 = 500x
47500 = 500x
x= 47500/500
x=95

95% of students are present.
