Step-by-step explanation:

Givens

Total number of students = 90Number of students who did pass = 24Number of students that did not pass = ?

Solution

Number of students who did not pass = Total - Those who didNumber not passing = 90 - 24 = 66Ratio = 24 / 66
Find the highest common factor by factoring down to primes.24: 2 * 2 * 2 * 366: 2 * 3 * 11
The bolded numbers are the highest common factor: 2 * 3 = 6Take out the bolded numbers and record what is left2*2 / 11 = 4/11
