Question

in Mrs. Dawson's class, 16 out of 24 students made at least an 80% on the last math test. Write a ratio in simplest form comparing the number of students who scored below an 80% to the total number of students.

Answer 1

16:24 students made at least 80% on the test. The question is what is the ratio of students who scored below an 80% to the total number of students. 8:24 would be the right answer, but since it is asking for the answer in the simplest form, it would be 1:3.

Answer 2

Since there are 16 who scored 80% and higher, then 24-16 = 8 students who didnt reach 80%;

Then the ratio of those who didnt get 80% to the total students is:
8:24

or 1:3
