Explanation:

There are several methods one could use. I will provide one.
$\frac{4}{5}$ $4/5$ is equal to $20 %$ $20%$ . $20$ $20$ goes into $100$ $100$ five times.
$\frac{100}{20} = 5$ $100/20=5$
Determine, then, what $\frac{4}{5}$ $4/5$ of $15$ $15$ is by determining what number goes into $15$ $15$ five times.
$\frac{15}{5} = 3$ $15/5 = 3$
$3$ $3$ goes into $15$ $15$ five times.
$\frac{5}{5}$ $5/5$ of $15 = 15$ $15 = 15$
$\frac{4}{5}$ $4/5$ of $15 = 12$ $15 = 12$ because $4 \cdot 3 = 12$ $4*3 = 12$
$15 - 12 = 3$ $15-12 = 3$
So, $\frac{4}{5}$ $4/5$ , or $3$ $3$ , of the dolls do not have brown hair.
