Question

If 72 is 40% what is 100%?

Answer 1

180

Explanation:

If 40% = 72, 100% can be found like so:

40% = 72

100% =
`(100)/(1)` *
`(72)/(40)`

You can reduce 40 and 100 by 20 (or probably more, but I'll use 20)

So now we have:

`(50)/(1)` *
`(72)/(20)` =
`(3600)/(20)`

Divide, and you get 180.

To check, we can find 40% of 180.

Hope this helps!
