Answer:

Answer: 4/11

Step-by-step explanation:

Givens

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

Solution

  • Number of students who did not pass = Total - Those who did
  • Number not passing = 90 - 24 = 66
  • Ratio = 24 / 66

  • Find the highest common factor by factoring down to primes.
  • 24: 2 * 2 * 2 * 3
  • 66: 2 * 3 * 11

  • The bolded numbers are the highest common factor: 2 * 3 = 6
  • Take out the bolded numbers and record what is left
  • 2*2 / 11 = 4/11
