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...24รท4=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?

To get the parentage you divide 18 by 24 and you get 0.75.
P.S I will help with everyone's questions if I have time or if I can. :) 
13 people take a test & 11 passed what percentage passed
