What is 16.5 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 16.5% of the output value, so we can write it down as x=16.5%.
5. Now we have two simple equations:
1) 520=100%
2) x=16.5%
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%/16.5%
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 16.5% of 520

520/x=100/16.5
(520/x)*x=(100/16.5)*x       - we multiply both sides of the equation by x
520=6.0606060606061*x       - we divide both sides of the equation by (6.0606060606061) to get x
520/6.0606060606061=x
85.8=x
x=85.8

now we have:
16.5% of 520=85.8
