Can u guys please do this question. THIS IS URGENT.
In a class of 36 pupils, the ratio of passes to failures in the final exam was 8: 1. How many pupils passed the exam?

Answer 1

Step-by-step explanation:

Total number of pupil in a class = 36

pass : fail = 8 : 1

let number of pupil passed = 8x

let number of pupil failed = x

8x + x = 36

9x = 36

x = 36/9

x = 4

so.... number of pupil passed = 8x = 8 × 4 = 32

number of pupil failed = x = 4
