Part A: 3/5 of the girls.
Hoped this helped.
oh haha! Good question.
Part A: What fraction of the girls in the class have long brown hair?
What's the question?
WHAT ABT PT B
To find the fraction of girls in the class who have brown hair, multiply the fraction of girls with brown hair by the total fraction of girls in the class:
Fraction of girls with brown hair = (4/5) = 0.8
Next, to find the fraction of girls with long brown hair, multiply the fraction of girls with brown hair by the fraction of girls with long hair:
Fraction of girls with long brown hair = (0.8) * (3/4) = 0.6
Finally, to find the fraction of girls with long brown hair and green eyes, multiply the fraction of girls with long brown hair by the fraction of girls with green eyes:
Fraction of girls with long brown hair and green eyes = (0.6) * (1/3) = 0.2
Therefore, 20% of the girls in the class have long brown hair and green eyes.
