Answer 1

Answer:

Step-by-step explanation:

We have that,

Fraction of girls having brown hair = $\frac{4}{5}$

Fraction of girls having long hair = $\frac{4}{5}$

Thus, the fraction of girls having long brown hair = Fraction having brown hair × Fraction having long hair

i.e. Fraction of girls having long brown hair = $\frac{4}{5}\times \frac{4}{5}$

i.e. Fraction of girls having long brown hair = $\frac{3}{5}$

Hence, the fraction of girls having long brown hair is  $\frac{3}{5}$.

ANSWER: 12/20 or 3/5

4/5 of girls have brown hair
3/4 have long hair

$\frac{4}{5} * \frac{3}{4} = \frac{12}{20}$
$\frac{12}{20} / \frac{4}{4} = \frac{3}{5}$
