The number is $37.5$ $37.5$

You can write an equation and solve it:

$4 % of something = 15$ $4% "of something" = 15$

$\frac{4}{100} \times x = 15$ $4/100 xx x = 15$

$x = \frac{15 \times 100}{4}$ $x = (15xx100)/4$

$x = 37.5$ $x = 37.5$

You can also write a direct proportion:

$\frac{4}{15} = \frac{100}{x} \frac{\leftarrow percent}{\leftarrow number}$ $4/15 = 100/x" "(larr"percent")/(larr " number")$

$x = \frac{15 \times 100}{4}$ $x = (15xx100)/4$

$= 37.5$ $=37.5$
