What is 54.9 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 54.9% of the output value, so we can write it down as x=54.9%.
5. Now we have two simple equations:
1) 520=100%
2) x=54.9%
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%/54.9%
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 54.9% of 520

520/x=100/54.9
(520/x)*x=(100/54.9)*x       - we multiply both sides of the equation by x
520=1.8214936247723*x       - we divide both sides of the equation by (1.8214936247723) to get x
520/1.8214936247723=x
285.48=x
x=285.48

now we have:
54.9% of 520=285.48
