What is 13 percent of 21164 - 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 21164 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 21164 is 100%, so we can write it down as 21164=100%.
4. We know, that x is 13% of the output value, so we can write it down as x=13%.
5. Now we have two simple equations:
1) 21164=100%
2) x=13%
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:
21164/x=100%/13%
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% of 21164

21164/x=100/13
(21164/x)*x=(100/13)*x       - we multiply both sides of the equation by x
21164=7.6923076923077*x       - we divide both sides of the equation by (7.6923076923077) to get x
21164/7.6923076923077=x
2751.32=x
x=2751.32

now we have:
13% of 21164=2751.32
