# How do you write 4/20 as a percent?

Dec 7, 2017

See a solution process below:

#### Explanation:

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

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

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

$\frac{4}{20} \times \textcolor{red}{100} = \frac{x}{100} \times \textcolor{red}{100}$

$\frac{400}{20} = \frac{x}{\textcolor{red}{\cancel{\textcolor{b l a c k}{100}}}} \times \cancel{\textcolor{red}{100}}$

$20 = x$

$x = 20$

4/20 = 20/100 = 20%

It's 20%.

#### Explanation:

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

First: take the denominator $\left(20\right)$ 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 $\left(4\right)$, which will just give you $20$.

Third: you got your answer of $\frac{20}{100}$ or just 20%.
