What is 520 percent of 407.5 - 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 407.5 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 407.5 is 100%, so we can write it down as 407.5=100%.
4. We know, that x is 520% of the output value, so we can write it down as x=520%.
5. Now we have two simple equations:
1) 407.5=100%
2) x=520%
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:
407.5/x=100%/520%
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 520% of 407.5

407.5/x=100/520
(407.5/x)*x=(100/520)*x       - we multiply both sides of the equation by x
407.5=0.19230769230769*x       - we divide both sides of the equation by (0.19230769230769) to get x
407.5/0.19230769230769=x
2119=x
x=2119

now we have:
520% of 407.5=2119
