Question

Mr.Jones grades 12 exams in 2 hours at the rate how many hours would it take to grade 48 exams

Answer 1

8 hours

Explanation:

Let's use the proportion 12/2 = 48/x

48/12 is 4 so then you would multiply 2 by 4

4 x 2 = 8

x = 8

Answer 2

8 Hours

Explanation:

So, if we know that 12 exams are graded in 2 hours. Then we just divide 48 by 12.

`48/12=4`

`4*2=8`

It would take 8 hours to grade 48 exams.
