Question

If 30% of the students taking a module failed the practical test. The class has 130 students. How many students passed the test?

Answer 1

91 students passed the test.

Explanation:

We need to find 10% of 130.

130÷10=13

Then we need to make it 30% in order to see the amount of students that failed the test.

13×3=39

Then we need to do 130 - 39 (The whole class- 30%)

130-39=91

Answer 2

91 students passed the test.

Explanation:

130 / 10 = 13

13 x 3 = 39

130 - 39 = 91
