Final answer:

To find the fraction of the class that are girls with a girl-to-boy ratio of 3:5, calculate 3 parts for girls out of the total 8 parts, which simplifies to ⅓ of the class.

Step-by-step explanation:

In the scenario where the ratio of girls to boys in a class is 3:5, we first add together the parts of the ratio to determine the total number of parts representing the whole class (3 parts for girls plus 5 parts for boys equals 8 parts in total). To find out what fraction of the class are girls, we divide the number of parts for girls by the total number of parts.

Let's do the math:

Number of parts for girls = 3
Total number of parts (girls + boys) = 3 + 5 = 8

Thus, the fraction representing the girls is:

3 (girls' parts) / 8 (total parts) = ⅓ of the class are girls.
