Percents

Yuki888 [10]

Answer:

Percentage: 115%

Decimal: 1.15

Fraction: $\frac{23}{20}\\$

Step-by-step explanation:

<u>Percentages, Fractions, and Decimals</u>

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% = $\frac{115}{100}$

Simplifying by 5:

115% = $\frac{23}{20}$
