109.18 is what 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 100% equals 520, so we can write it down as 100%=520.
4. We know, that x% equals 109.18 of the output value, so we can write it down as x%=109.18.
5. Now we have two simple equations:
1) 100%=520
2) x%=109.18
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:
100%/x%=520/109.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 109.18 is what percent of 520

100%/x%=520/109.18
(100/x)*x=(520/109.18)*x       - we multiply both sides of the equation by x
100=4.7627770653966*x       - we divide both sides of the equation by (4.7627770653966) to get x
100/4.7627770653966=x
20.996153846154=x
x=20.996153846154

now we have:
109.18 is 20.996153846154% of 520
