7.22 is what percent of 415 - 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 415 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 415, so we can write it down as 100%=415.
4. We know, that x% equals 7.22 of the output value, so we can write it down as x%=7.22.
5. Now we have two simple equations:
1) 100%=415
2) x%=7.22
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%=415/7.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.22 is what percent of 415

100%/x%=415/7.22
(100/x)*x=(415/7.22)*x       - we multiply both sides of the equation by x
100=57.479224376731*x       - we divide both sides of the equation by (57.479224376731) to get x
100/57.479224376731=x
1.7397590361446=x
x=1.7397590361446

now we have:
7.22 is 1.7397590361446% of 415
