Three-fourths of the class were girls.
Two-thirds of the girls have dark hair.
What fractions of the class is female and dark haired?
3/4 * 2/3 = ?
To find the fraction of the class that is female and dark haired, we need to multiply the fractions for the proportion of girls and the proportion of girls with dark hair.
The fraction of the class that is girls is three-fourths, or 3/4.
The fraction of the girls with dark hair is two-thirds, or 2/3.
To find the fraction of the class that is female and dark haired, we multiply these two fractions.
(3/4) * (2/3) = (3 * 2) / (4 * 3) = 6/12
Therefore, the fraction of the class that is female and dark-haired is 6/12, or simplified to 1/2.
To find the fraction of the class that is female and dark-haired, we need to multiply the fractions representing the proportion of the class that are girls and the proportion of girls that have dark hair.
First, let's determine the fraction that represents the proportion of the class that are girls. We are given that three-fourths of the class are girls, which can be represented as 3/4.
Next, we need to find the fraction that represents the proportion of girls that have dark hair. We are given that two-thirds of the girls have dark hair, so this can be represented as 2/3.
To find the fraction of the class that is both female and dark-haired, we multiply the fractions: (3/4) * (2/3) = 6/12 = 1/2.
Therefore, one-half or 1/2 of the class is female and dark-haired.
