What is 26.4 percent of 520 - 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 520 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 520 is 100%, so we can write it down as 520=100%.
4. We know, that x is 26.4% of the output value, so we can write it down as x=26.4%.
5. Now we have two simple equations:
1) 520=100%
2) x=26.4%
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:
520/x=100%/26.4%
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 26.4% of 520

520/x=100/26.4
(520/x)*x=(100/26.4)*x       - we multiply both sides of the equation by x
520=3.7878787878788*x       - we divide both sides of the equation by (3.7878787878788) to get x
520/3.7878787878788=x
137.28=x
x=137.28

now we have:
26.4% of 520=137.28
