58 is what percent of 221 - 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 221 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 221, so we can write it down as 100%=221.
4. We know, that x% equals 58 of the output value, so we can write it down as x%=58.
5. Now we have two simple equations:
1) 100%=221
2) x%=58
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%=221/58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 58 is what percent of 221

100%/x%=221/58
(100/x)*x=(221/58)*x       - we multiply both sides of the equation by x
100=3.8103448275862*x       - we divide both sides of the equation by (3.8103448275862) to get x
100/3.8103448275862=x
26.244343891403=x
x=26.244343891403

now we have:
58 is 26.244343891403% of 221
