15.25 is what percent of 305.05 - 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 305.05 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 305.05, so we can write it down as 100%=305.05.
4. We know, that x% equals 15.25 of the output value, so we can write it down as x%=15.25.
5. Now we have two simple equations:
1) 100%=305.05
2) x%=15.25
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%=305.05/15.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.25 is what percent of 305.05

100%/x%=305.05/15.25
(100/x)*x=(305.05/15.25)*x       - we multiply both sides of the equation by x
100=20.003278688525*x       - we divide both sides of the equation by (20.003278688525) to get x
100/20.003278688525=x
4.9991804622193=x
x=4.9991804622193

now we have:
15.25 is 4.9991804622193% of 305.05
