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

Answer:

21%

Step-by-step explanation:

Formula for this type of problem is

$\frac{84}{400} = \frac{x}{100}$

cross multiply

$8400 = 400x$

divide by 400

$8400 = 400x$

/400   /400

$21 = x$

plug 21 into the original equation

$\frac{84}{400} = \frac{21}{100}$

simplify

$\frac{84}{100} = .21$

.21 can be represented as 21%

Answer 2

the answer to this is .21
