Answer 1

Answer:

25

Explanation:

We have the following information:

There are 15 females

The ratio of females to males is 3:2

The number of members in the club:

$\begin{gathered} 15\colon x=3\colon2 \\ \Rightarrow\frac{15}{x}=\frac{3}{2} \\ \text{Cross multiply, we have:} \\ 3x=15\times2 \\ 3x=30 \\ x=\frac{30}{3}=10 \\ x=10 \\ \Rightarrow The\text{ number of males in the club is 10} \end{gathered}$

There are 15 females and 10 males. Therefore, the total numbers of members in the club is given:

$\begin{gathered} =15+10 \\ =25 \\ \\ \therefore The\text{ total number of members in the club is 25 } \end{gathered}$

Therefore, there are 25 members in the club
