Mr. jones has 12exams in 2 hours. At that rate how many hours would it take to grade 48 exams

Solution:

Given that,

Mr.jones has 12 exams in 2 hours

From given,

12 exams ⇒ 2 hours

At that rate how many hours would it take to grade 48 exams

Let "x" be the time taken for 48 exams

Therefore,

12 exams ⇒ 2 hours

48 exams  ⇒ "x" hours

This forms a proportion and solve the sum by cross multiplying

Thus it takes 8 hours to grade 48 exams
