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?

Answer 1

If the lightest is x, then the heaviest is 3x. So,
3x = x+8
x = 4

So, the parts are 4,8,12 oz
