The number of boys to girls any grade level is 7:2. If there are 48 girls in the grade level how many boys are there ?
7/2=x/48
2x=329
x=164.6 ~ 165 boys
number of boys --- 7x
number of girls --- 2x
2x = 48
x = 24
number of boys = 7x
= 7(24)
= 168
there are 168 boys.
your ratio equation should have been
7/2 = x/48
2x = 336
x = 168
To find the number of boys in the grade level, we'll first need to determine the ratio of boys to girls. The given information states that the ratio of boys to girls is 7:2. This means that for every 7 boys, there are 2 girls.
Next, we're given that there are 48 girls in the grade level. We can use this information to find the number of boys.
To find the number of boys, we'll set up a proportion using the ratio of boys to girls:
7 boys / 2 girls = x boys / 48 girls
Cross multiplying, we get:
7 * 48 = 2 * x
336 = 2x
Dividing both sides of the equation by 2, we find:
x = 336 / 2
x = 168
Therefore, there are 168 boys in the grade level.
