Question

4/5 of the students in a class do History. If there are 16 students who do

History, how many students are there in the class?

Answer 1

20 students

Explanation:

4/5 of a class is 16 students. That means that 1/5 of a class consists of 4 people. 5 * 4 is 20. If we want to cross check, 4/5 of 20 is 16. So there are 20 students in a class.

Answer 2

Answer: 20

Explanation:

We know that 4/5 here is 16 students. So we have to find 1/5 by 16 divided by 4 and we get that 1/5 is 4 students. So 4 times 5 is equal to 20. So there are 20 students.
