Question

If 100=120% of x, what is x?

Answer 1

`83.bar3`

Explanation:

Let's rearrange the question into an equation.

Here are some tips to start:

1. The word "of" means multiplication, so you can just put a `xx` sign wherever you see the word "of".
2. `120%` is the same as `120/100` as a fraction or `1.20` as a decimal. I'll be using the decimal form in the equation.

Original:
`100 = 120%` of `x`

New:
`100 = 1.2xxx`

Divide both sides by `1.2` to isolate `x`.

`100 = 1.2x`

`100/1.2 = (cancel(1.2)x)/cancel1.2`

`83.bar3 = x`

The line over the #3 indicates that it repeats forever.
