If half of a box of candy weighs 3/5 of a pound, how much would 4 full boxes weigh?
Reil [10]
So we want to know what a full box is. We have the weight of half a box. So we can use the formula: (2 x 3/5) and you want to know the outcome of four full boxes. So (2x3/5)4
Or: 6/5 x 4

And the answer is 24/5. But if you want to simplify it, it’s 4 4/5
