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%
