Question

What percent of 60 is 18?

Answer 1

See a solution process below:

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as `x/100`.

So we can write:

`x/100 = 18/60` where `x` is the percent.

Now, multiply each side of the equation by `color(red)(100)` to solve for `x` while keeping the equation balanced:

`color(red)(100) xx x/100 = color(red)(100) xx 18/60`

`cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = 1800/60`

`x = 30`

18 is `color(red)(30%)` of 60
