Explanation:

Percentages, Fractions, and Decimals

Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

Now we express 115% as a decimal, simply dividing by 100:

115% = 115/100 = 1.15

To express it as a fraction, we simplify the division instead of calculating it:

115% =
`(115)/(100)`

Simplifying by 5:

115% =
`(23)/(20)`
