I ate 2/5 of my pizza what percent did i eat?

You most likely ate 40% of your pizza

Step-by-step explanation:

You ate 40%. I know this because you need to make the denominator one hundred. 5 times 20 equals 100. You then mulyiply 2 by 20 because you have to do the same for both. Then that is 40/100 which equals 40%.
