31.92 is what percent of 231 - 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 231 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 231, so we can write it down as 100%=231.
4. We know, that x% equals 31.92 of the output value, so we can write it down as x%=31.92.
5. Now we have two simple equations:
1) 100%=231
2) x%=31.92
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%=231/31.92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.92 is what percent of 231

100%/x%=231/31.92
(100/x)*x=(231/31.92)*x       - we multiply both sides of the equation by x
100=7.2368421052632*x       - we divide both sides of the equation by (7.2368421052632) to get x
100/7.2368421052632=x
13.818181818182=x
x=13.818181818182

now we have:
31.92 is 13.818181818182% of 231
