2/10 * 1/2 = ?
To find the fraction of red-haired girls in the fifth-grade class, we need to determine the ratio of red-haired girls to the total number of students in the class.
First, let's calculate the number of girls in the fifth-grade class. If girls make up one-half of the entire class, we can find their fraction by dividing it by 2: 1/2.
Next, we need to determine the fraction of girls with red hair. We know that two-tenths of the girls have red hair, which can be written as 2/10.
To find what fraction of the fifth-grade class has red hair, we need to multiply the fraction of girls (1/2) by the fraction of red-haired girls (2/10). Multiplying these two fractions, we get:
(1/2) * (2/10) = 2/20 = 1/10.
Therefore, red-hair girls make up 1/10th of the entire fifth-grade class.
