Question

In math class 20% of the students did not finish their quiz. If 24 students finished their quiz, how many students are in math class?

Answer 1

Answer: 30 kids are in the math class

Step-by-step explanation: A simple way to solve this question is by knowing divisors. Since 24 is only 80% of X, then look for common divisors betweet 24 and 80% (4) If 6 is 20%, then 30 is 100%

Answer 2

30 as 24=80% so 10%= 3, 3x2=6/20% 24+6=30
