Question

Answer 1

25

Step-by-step 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(15)/(x)=(3)/(2) \\ \text{Cross multiply, we have:} \\ 3x=15*2 \\ 3x=30 \\ x=(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
