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.
 Austin has answered of the questions.
=
Austin has answered 60 questions, or 60%.
n = 60  Cheyenne has answered 10 fewer questions than Austin:
60 − 10 = 50
Cheyenne has answered 50 questions out of 100:
50%, or  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
Kareema has answered 30 questions.  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:
=  Madeline has answered 6 more questions than Kareema.
Kareema answered 30: 30 + 6 = 36
Madeline answered 36 questions. To show as a fraction:
