ANSWER: 12/20 or 3/5
4/5 of girls have brown hair
3/4 have long hair
\(\frac{4}{5} * \frac{3}{4} = \frac{12}{20}\)
\(\frac{12}{20} / \frac{4}{4} = \frac{3}{5}\)
Answer:
\(\frac{3}{5}\)
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 \(\frac{3}{5}\).
