25.5 is what percent of 519.65 - 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 519.65 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 519.65, so we can write it down as 100%=519.65.
4. We know, that x% equals 25.5 of the output value, so we can write it down as x%=25.5.
5. Now we have two simple equations:
1) 100%=519.65
2) x%=25.5
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%=519.65/25.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.5 is what percent of 519.65

100%/x%=519.65/25.5
(100/x)*x=(519.65/25.5)*x       - we multiply both sides of the equation by x
100=20.378431372549*x       - we divide both sides of the equation by (20.378431372549) to get x
100/20.378431372549=x
4.9071490426248=x
x=4.9071490426248

now we have:
25.5 is 4.9071490426248% of 519.65
