Question

78 % of the class scored a C or above on their test. If there are 35 students in the class, how many scored a C or higher? Write and solve a proportion for this situation.

Answer 1

27 students

Explanation:

`(78)/(100) =(x)/(35) \\`

cross multiply and you get 27

Answer 2

All this question is trying to ask is to find 78% percent of the total number of student in the class.

So first convert 78 to decimal by dividing it by 100:
`(78)/(100) = 0.78`

Next multiply that with the total number of students which is 35.

So,
`0.78 * 35 = 27.3`

Now I don't think there can be a decimal here. The question must be wrong or the percentage might be incorrect. But, just for sake, we'll round it up so the final answer would be:
`27`

The proportion would be:
`273:10`
