There are 28 students in math class. 22 of them passed the test. what percentage passed the test?

You'll have to divide the students that passed by the total number of students and then multiply the answer by 100.

(22/28)*100 = 78.57%

So 78.57% students passed.

Hope this helps :)

Hello there!

100% = 28 students
    x% = 22

Cross multiply

28 * x = 22 * 100

28x = 2200

x = 2200/28

x = 78.57

Thus,

78.57% of the students passed the test.
