517.5 is what percent of 4225 - 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 4225 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 4225, so we can write it down as 100%=4225.
4. We know, that x% equals 517.5 of the output value, so we can write it down as x%=517.5.
5. Now we have two simple equations:
1) 100%=4225
2) x%=517.5
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:
100%/x%=4225/517.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 517.5 is what percent of 4225

100%/x%=4225/517.5
(100/x)*x=(4225/517.5)*x       - we multiply both sides of the equation by x
100=8.1642512077295*x       - we divide both sides of the equation by (8.1642512077295) to get x
100/8.1642512077295=x
12.248520710059=x
x=12.248520710059

now we have:
517.5 is 12.248520710059% of 4225
