Your waiter at a restaurant suggests you leave a tip of $10 on a $50 bill. What percentage is that?
Bezzdna [24]

Answer:

20%

Step-by-step explanation:

To find what percentage is $10 out of $50, we divide 10 by 50:

\frac{10}{50}=0.2

If we want to get the result in percentage form, we simply multiply it by 100%:

0.2\cdot 100\%=20\%

So a tip of $10 on a $50 bill is a tip of 20%.
