<PRE><B>Question 524681</B>
If 45% of the students in a course made an A; 35% made a B; and the remaining 12 students made a C, how many students in the course made an A?
------
The 12 students represent 100%-[45%+35%] = 20%
----
Let x be the total number of students:
Equation:
0.20x = 12
x = 12/0.2 = 120/2 = 60
---
# who made A = 0.45*60 = 27
