Question

Last quarter, 84 seventh grade students made honor roll. If there are 400 students in the seventh grade, what percent made honor roll?

Answer 1

the answer to this is .21

Answer 2

21%

Explanation:

Formula for this type of problem is

`(84)/(400) = (x)/(100)`

cross multiply

`8400 = 400x`

divide by 400

`8400 = 400x`

/400 /400

`21 = x\\`

plug 21 into the original equation

`(84)/(400) = (21)/(100)`

simplify

`(84)/(100) = .21`

.21 can be represented as 21%
