# What percent of 40 is 28?

Jan 13, 2017

70%

#### Explanation:

We consider the percent as $x$. Hence:

$40 \times \frac{x}{100} = 28$

$4 \cancel{0} \times \frac{x}{10 \cancel{0}} = 28$

Multiply both sides by $\frac{10}{4}$.

$x = 28 \times \frac{10}{4}$

$x = 7 \cancel{28} \times \frac{10}{1 \cancel{4}}$

$x = 70$
