What is 68.75 percent of 13.2 - 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 13.2 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 13.2 is 100%, so we can write it down as 13.2=100%.
4. We know, that x is 68.75% of the output value, so we can write it down as x=68.75%.
5. Now we have two simple equations:
1) 13.2=100%
2) x=68.75%
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:
13.2/x=100%/68.75%
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 68.75% of 13.2

13.2/x=100/68.75
(13.2/x)*x=(100/68.75)*x       - we multiply both sides of the equation by x
13.2=1.4545454545455*x       - we divide both sides of the equation by (1.4545454545455) to get x
13.2/1.4545454545455=x
9.075=x
x=9.075

now we have:
68.75% of 13.2=9.075
