Answer 3

Calculation of the Number of Boys and Girls in the Children's Choir

To calculate the number of boys and girls in the children's choir, we can follow these steps:

1. Let's denote the number of boys as B and the number of girls as G. 2. We are given that the number of girls in the choir is 4 times the number of boys: G = 4B. 3. We are also given that the number of boys is 36 less than the number of girls: G - B = 36.

Solving the Equations

We can solve these two equations to find the values of B and G.

First, we can substitute the value of G from the first equation into the second equation:

4B - B = 36

This simplifies to:

3B = 36

So, the number of boys, B, is:

B = 36 / 3 = 12

Now that we have the value of B, we can find the number of girls, G, using the first equation:

G = 4 * 12 = 48

Conclusion

Therefore, there are 12 boys and 48 girls in the children's choir.
