• D. The fraction of girls is $\frac{1}{4}$ and the ratio of girls to boys is $\frac{1}{4}$

Answer 1

The correct option is A

The fraction of boys is $\frac{4}{5}$ and the ratio of boys to girls is $\frac{4}{1}$

A fraction is a number that represents a part of a whole or a part of a group.

In a group of five students with 4 boys and 1 girl, the fraction of girls is $\frac{1}{5}$. The fraction of boys is $\frac{4}{5}$. The denominator will always be five because the whole group consists of five students.

In the example given above, the ratio of girls to boys is 1:4 and the ratio of the number of boys to the number of girls is 4:1. The ratio of girls to the total number of students is 1:5, and the ratio of boys to the total number of students is 4:5.
