# Out of 30 problems on a test, Jose got 4 wrong What percentage did Jose get correct?

Nov 3, 2016

Jose got 86.7% of the problems correct.

#### Explanation:

Percentage means "per 100" or "out of 100" so we can write this problem as:

$\frac{30 - 4}{30} = \frac{x}{100}$: Using $\left(30 - 4\right)$ because the question is about the percentage correct and to get the percentage correct you need to know the number correct not the number wrong ($4$).

$\frac{26}{30} = \frac{x}{100}$

$\frac{100 \cdot 26}{30} = x$

$\frac{2600}{30} = x$

$x = 86.7$
