Question

I have a 20oz bottle of water and I drank 8oz what's the ,% of what's left?

Answer 1

We need to calculate first the number of ounces left in the bottle:

20 oz - 8 oz = 12 oz.

Now we want to find what percent (x) of 20 oz is the left amount 12 oz.

So we use the expression for percent:

x times 20 = 12

x * 20 = 12

Therefore solving for x we get:

x = 12/20

x = 0.6

which in percent corresponds to 60%
