221.67 is what percent of 555.77 - 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 555.77 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 555.77, so we can write it down as 100%=555.77.
4. We know, that x% equals 221.67 of the output value, so we can write it down as x%=221.67.
5. Now we have two simple equations:
1) 100%=555.77
2) x%=221.67
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%=555.77/221.67
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 221.67 is what percent of 555.77

100%/x%=555.77/221.67
(100/x)*x=(555.77/221.67)*x       - we multiply both sides of the equation by x
100=2.5071953805206*x       - we divide both sides of the equation by (2.5071953805206) to get x
100/2.5071953805206=x
39.885204311136=x
x=39.885204311136

now we have:
