Question

72% of what weight is 50 oz?

Answer 1

Well, when we put it into an equation,

`0.72 = (72%)/(100%)`,

so that

`0.72 xx "weight (oz)" = "50 oz"`.

"Of" indicates a multiplication, and "what weight"? Call it `x`, or whatever you want.

Therefore, the original weight was:

`color(blue)"weight" = ("50 oz")/(0.72) = color(blue)"69.4 oz"`

If you take `72%` of this, do you get `"50 oz"` back?
