Question

19% of what is 117.5?

Answer 1

Approximately, `618.42`

Explanation:

Assume an unknown quantity is `X`.
Then `19%` (or `0.19`) of this quantity is `117.5`.

Therefore, we can represent it in an equation:
`0.19 * X = 117.5`

To solve this equation, recall that both sides of an equation can be divided by the same number not equal to 0 and get a new equation.
Let's divide both sides of our equation by `0.19`:

`(0.19*X)/0.19 = 117.5/0.19`

which can be transformed into
`X*0.19/0.19 = 117.5/0.19`

or, since `0.19/0.19=1` and `117.5/0.19~~618.42`,

`X ~~ 618.42`
