4/5 of girls have brown hair
3/4 have long hair
[tex] \frac{4}{5} * \frac{3}{4} = \frac{12}{20} [/tex]
[tex] \frac{12}{20} / \frac{4}{4} = \frac{3}{5} [/tex]
4/5 of girls have brown hair
3/4 have long hair
[tex] \frac{4}{5} * \frac{3}{4} = \frac{12}{20} [/tex]
[tex] \frac{12}{20} / \frac{4}{4} = \frac{3}{5} [/tex]
Answer:
[tex]\frac{3}{5}[/tex]
Step-by-step explanation:
We have that,
Fraction of girls having brown hair = [tex]\frac{4}{5}[/tex]
Fraction of girls having long hair = [tex]\frac{4}{5}[/tex]
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 = [tex]\frac{4}{5}\times \frac{4}{5}[/tex]
i.e. Fraction of girls having long brown hair = [tex]\frac{3}{5}[/tex]
Hence, the fraction of girls having long brown hair is [tex]\frac{3}{5}[/tex].
