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.
