See a solution process below:

"Percent" or "%" means "out of 100" or "per 100", Therefore x% can be written as $\frac{x}{100}$ $x/100$ .

So we can write the equation and solve for $x$ $x$ as:

$\frac{4}{20} = \frac{x}{100}$ $4/20 = x/100$

$\frac{4}{20} \times 100 = \frac{x}{100} \times 100$ $4/20 xx color(red)(100) = x/100 xx color(red)(100)$

$400/20= x/color(red)(cancel(color(black)(100))) xx cancel(color(red)(100))$

$20 = x$

$x = 20$

$4/20 = 20/100 = 20%$

It's $20%$ .

A percent is something out of $100$ , so here's what you're going to do:

First: take the denominator $(20)$ and multiply it by something that will give you a hundred, which is just $5$ .

Second: you take that $5$ and multiply it by your numerator $(4)$ , which will just give you $20$ .

Third: you got your answer of $20/100$ or just $20%$ .
