Question

Challenger Elementary School has 800 students. Every Wednesday, 12 percent of the students stay after school for Chess Club.

Answer 1

Let's set up a proportion.

$\frac{x}{800} \frac{12}{100}$

Then solve for x:
12 x 800 = 9600
9600/100 = 96

96 is 12% of the 800 students. :)

Answer 2

First you will need to set up your equation. Your 800 students is equal to 100% and x is equal to your 12%. Your equation should be set up similarly:

   x            12
___    =   ___
800        100

Next you will cross multiply. You will multiply x with 100 and 12 with 800.

100 * x = 12 * 800
100x = 9,600

Finally, you will make x equivalent to 1. You do this by dividing both sides of the equation by 100.

100x = 9,600
/ 100     /100
x = 96

If you have done your equation properly then your answer should come out to 96 students.
