The ratio of the number of boys to the number of girls in a choir is 5 to 4. There are 60 girls in the choir.
How many boys are in the choir?
5:4 = 75:60
To find the number of boys in the choir, we need to use the ratio of boys to girls. The ratio given is 5 to 4, which means there are 5 boys for every 4 girls.
Since we know there are 60 girls in the choir, we can set up a proportion to find the number of boys.
5 boys / 4 girls = X boys / 60 girls
To solve for X (the number of boys), we can cross multiply and solve for X.
5 boys * 60 girls = 4 girls * X boys
300 boys = 4X
To isolate X, we divide both sides of the equation by 4:
300 boys / 4 = X
75 boys = X
So, there are 75 boys in the choir.
To find the number of boys in the choir, we need to use the given ratio and the number of girls in the choir.
The ratio of boys to girls is 5 to 4, which means for every 5 boys, there are 4 girls.
It is given that there are 60 girls in the choir.
Now, we can set up a proportion to find the number of boys.
Let's represent the number of boys as 'x'.
5/4 = x/60
To solve for 'x', we can cross-multiply:
4x = 5 * 60
4x = 300
Divide both sides by 4:
x = 300/4
x = 75
Therefore, there are 75 boys in the choir.
