Sally bought the pizza shown above for lunch, which is cut into 10 equal slices. what percentage of the pizza did sally eat if she had six slices?

a) 40%
b) 50%
c) 60%
d) 70%

We can represent the pizza as 1. And every time we take a slice, we take percentage away. This pizza is cut up equally into 10 slices. So, if we take away a slice, we take away 1/10 of the pizza. What if Sally ate 6 slices? Same difference. She took away 6/10 of the pizza.

And to answer the question, "What percentage of the pizza did Sally eat if she had six slices?"

We will convert the 6/10 into a percentage. First convert the fraction into a decimal then into a percent.

To convert a fraction into a decimal, simply divide it's numerator by it's denominator.

6/10 = 0.60

And to convert a decimal into a percentage, move the decimal point two places to the right and change it into a % sign.

0.60 = 60%

So, the answer to this question C) 60%

If you are still confused, DM me and I'll do my best to help!

"Percent" means per one hundred, so you can say:

p/100=6/10

p=600/10

p=60%
