Answer
$20%$
Work Step by Step
We have:
$\text{part}=x\cdot \text{whole}$
where $x$ is the percent which the part represents from the whole.
Let $x$ be the percent we are looking for. Here the part is $10$ and the whole is $50$.
$x\cdot50=10$
Divide both sides by $50$ to isolate $x$ and simplify the fraction:
$x=\frac{10}{50}=\frac{1}{5}$
Convert fraction into percent:
$\frac{1}{5}=20\%$
