Question 210951
Thirty three out of 198 students surveyed said they preferred hockey to all other sports. What fraction of students surveyed is this? 
---
If you are studying division, divide 33 by 198 to get the percentage.
If you are studying algebra, set up a proportion as follows:
x/100 = 33/198
x = 100(33/198)
x = 16.67%
================================

In high school 25 percent of the girls and 50 percent of the boys attended a football game. If 48 percent of all the students in the school are girls, what percent of all the students went to the football game?
Let x be the number in the school.
# of girls is 0.48x
# of boys is 0.52x
--------------------------
# of girls that went to the game = 0.25(0.48x) = 0.12x
# of boys who went to the game = 0.50(0.52x) = 0.26x
--------------------------
% of all students who went to the game = (0.12x+0.26x)/x = 0.38 = 38%
