# The ratio of boys and girls are 5 to 4. There are 60 girls how many boys

## Ratio of boys to girls is 5:4. We could change that to a fraction, which is 5/4.

We now set up a proportion. We will call the unknown number of boys (b):

5/4 = b/60

Solve: (5 x 60)/4 = 300/4 = 75 boys

Check: Since a ratio represents division, we can divide 75 by 60 and 5 by 4. If they are equal, then we have done it correctly.

75/60 = 1.25

5/4 = 1.25

So, there 75 boys.

Hope this helps! :)

## boys : girls = 5 : 4 = 5x : 4x

but 4x = 60, so x = 15

number of boys = 5x = 75

check:

boys:girls = 75:60 = 5 : 4

## To find out how many boys there are, we can set up a proportion using the given ratio.

The ratio of boys to girls is 5:4.

First, let's find the ratio of boys to total number of children:

5 + 4 = 9

So, the ratio of boys to total children will be 5:9.

Now, we can set up the proportion:

5/9 = x/60

To find 'x', we can cross-multiply:

5 * 60 = 9 * x

300 = 9x

Divide both sides by 9:

300/9 = x

x ≈ 33.33

Since we can't have a partial number of boys, we can round down to the nearest whole number.

Therefore, there are approximately 33 boys.

## To find the number of boys, we need to use the given ratio and the known number of girls.

The ratio of boys to girls is 5 to 4, which means for every 5 boys, there are 4 girls.

We are given that there are 60 girls, so we can set up a proportion to solve for the number of boys:

(B boys / 60 girls) = (5 boys / 4 girls)

To solve for B, we can cross-multiply:

B = (5 boys / 4 girls) * 60 girls

Now, we can simplify:

B = (5/4) * 60

B = 75

Therefore, there are 75 boys.
