There are 24 students in Mrs.Smith's 1st block class. 1/4 of the class passed the math test with an A. 12 students in the class passed the math test with a B. What percent of the students in the class passed the test?
This is how I slove the problem, but I stuck in the middle of the problem. Need help to find the percent of the students in the class passed the test.
First step: 1/4 students passed with an A...24÷4=6. So there are 6 students got an A.
Second step: 12 students passed with a B. Then add A & B (6+12=18) students and found out 18 students are passed the test.
But how to find the percentage?
