first find the fraction of blue green and yellow ball
1/8+1/4+1/12=3/24+6/24+2/24 common denominator
11/24 add numenators
the fraction of white ball =24/24-11/24=13/24
so fraction 13/24 correspond to 26 balls if x is total numbers of balls then
x=26×24/13=48 total numbers balls so blue balls = 1/8 of 48 =6
1/8+1/4+1/12=3/24+6/24+2/24 common denominator
11/24 add numenators
the fraction of white ball =24/24-11/24=13/24
so fraction 13/24 correspond to 26 balls if x is total numbers of balls then
