    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

    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 \[x=\frac{325*12}{25}=156 boys \]
