24:26 boys is the ratio
OpenStudy (anonymous):
not the ratio! how many boys there are!
OpenStudy (anonymous):
therefore if u simplify that ratio by dividing by 2 ull get 12:13.
Now the total no.of boys is 12/13+12*325
=12/25*325=156boys

i got 168
OpenStudy (anonymous):
well thats my best only answer as far as my experience
OpenStudy (s):
x = boys
26x/24 = girls
So, x + 26x/24 = 325
24x/24 + 26x/24 = 325
50x/24 = 325
50x = 325 * 24
50x = 7800
x = 7800 / 50
x = 156 - boys
26x/24 = 26*156/24 = 169 - girls

Set a proprtion
25 students - 12 boys
325 students - x boys
\[x=\frac{325*12}{25}=156 boys \]
