$30$ $30$

$40 %$ $40%$ is the same as $\frac{40}{100}$ $40/100$ , so taking the percent amount as $x$ $x$ we write:

$x = 75 \times \frac{40}{100}$ $x=75xx40/100$

Dividing the numerator and the denominator by $25$ $25$ , we get:

$x = 375 \times \frac{40}{4100}$ $x=3cancel75xx40/(4cancel100)$

$x = 3 \times \frac{40}{4}$ $x=3xx40/4$

Dividing the numerator and the denominator by $4$ $4$ , we get:

$x = 3 \times \frac{1040}{14}$ $x=3xx(10cancel40)/(1cancel4)$

$x = 3 \times 10$ $x=3xx10$

$x = 30$ $x=30$
