Question

On the last test, 40% of all sudents in Mrs. Well's class got an A. How many students are in this calss if there were 28 A's on the test?

Answer 1

70 students

Explanation:

If 40% of all students in Mrs. Well's class got an A, and 28 students got an A, that means that 28 = 40%

To find the total number of students, we need to find 100%

40% = 28

Divide by 4

10% = 7

Multiply by 10

100% = 70

So there are 70 students in Mrs. Well's class.

Hope this helps you! :D
