# Project Percents

## Solution

Name Fraction Percent
Austin 60%
Cheyenne 50%
Jasmine 25%
Kareema 30%

## Explanation

Make a chart to show the students' names, number of questions, number completed, fraction, decimal, and percent.

One way to find a percent is to use equivalent fractions.

Remember, percent (%) is a ratio that compares a number to 100.

To find the correct percent, write equivalent fractions in the form:

 Number of questions answered = n Total number of questions 100

n is equal to the number out of 100, or the percent.

Another way to find the percent is to divide the numerator by the denominator for a decimal. Multiply the decimal x 100 to find the percent.

1. Austin has answered of the questions. =
Austin has answered 60 questions, or 60%.

n = 60
2. Cheyenne has answered 10 fewer questions than Austin:
60 − 10 = 50
Cheyenne has answered 50 questions out of 100:
50%, or
3. Kareema has answered 0.3 of the questions:
0.3 = 0.3 x 100 = 30%
30% of the questions = 30 questions, or of the questions
4. Jasmine has answered half as many questions as Cheyenne.
Since Cheyenne answered 50, of 50 = 25.
Jasmine has answered 25 questions. To show as a fraction:
=
Kareema answered 30: 30 + 6 = 36
