Question

5 of the students in a history class failed a History test. If these students are 25% of all the students in the class, how many students are in the history class?

Answer 1

Explanation:

Let's say the total number of students in the history class is "x". We know that 5 students failed the test, which is 25% of the class.

So we can set up the following equation:

5 = 0.25x

To solve for "x", we can divide both sides by 0.25:

5/0.25 = x

20 = x

Therefore, there are 20 students in the history class.
