211.7 is what percent of 1139 - 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 1139 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 1139, so we can write it down as 100%=1139.
4. We know, that x% equals 211.7 of the output value, so we can write it down as x%=211.7.
5. Now we have two simple equations:
1) 100%=1139
2) x%=211.7
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%=1139/211.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 211.7 is what percent of 1139

100%/x%=1139/211.7
(100/x)*x=(1139/211.7)*x       - we multiply both sides of the equation by x
100=5.3802550779405*x       - we divide both sides of the equation by (5.3802550779405) to get x
100/5.3802550779405=x
18.586479367867=x
x=18.586479367867

now we have:
211.7 is 18.586479367867% of 1139
