What is 83.49 percent of 13 - 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 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 is 100%, so we can write it down as 13=100%.
4. We know, that x is 83.49% of the output value, so we can write it down as x=83.49%.
5. Now we have two simple equations:
1) 13=100%
2) x=83.49%
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/x=100%/83.49%
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 83.49% of 13

13/x=100/83.49
(13/x)*x=(100/83.49)*x       - we multiply both sides of the equation by x
13=1.1977482333214*x       - we divide both sides of the equation by (1.1977482333214) to get x
13/1.1977482333214=x
10.8537=x
x=10.8537

now we have:
83.49% of 13=10.8537
