What is 13.2 percent of 522 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 522 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 522 is 100%, so we can write it down as 522=100%.
4. We know, that x is 13.2% of the output value, so we can write it down as x=13.2%.
5. Now we have two simple equations:
1) 522=100%
2) x=13.2%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
522/x=100%/13.2%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 13.2% of 522

522/x=100/13.2
(522/x)*x=(100/13.2)*x       - we multiply both sides of the equation by x
522=7.5757575757576*x       - we divide both sides of the equation by (7.5757575757576) to get x
522/7.5757575757576=x
68.904=x
x=68.904

now we have:
13.2% of 522=68.904
