22 is what percent of 557 - 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 557 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 557, so we can write it down as 100%=557.
4. We know, that x% equals 22 of the output value, so we can write it down as x%=22.
5. Now we have two simple equations:
1) 100%=557
2) x%=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%=557/22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22 is what percent of 557

100%/x%=557/22
(100/x)*x=(557/22)*x       - we multiply both sides of the equation by x
100=25.318181818182*x       - we divide both sides of the equation by (25.318181818182) to get x
100/25.318181818182=x
3.9497307001795=x
x=3.9497307001795

now we have:
22 is 3.9497307001795% of 557
