This is an easy question but I can't find my notes on the subject. A cookie dough is divided into 3, in a ratio of 1:2:3 by weight. If the heaviest dough is 8oz more than the lightest one, what was the weight of the dough before dividing?
If the lightest is x, then the heaviest is 3x. So,
3x = x+8
x = 4
So, the parts are 4,8,12 oz
