21.31 is what percent of 9.137 - 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 9.137 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 9.137, so we can write it down as 100%=9.137.
4. We know, that x% equals 21.31 of the output value, so we can write it down as x%=21.31.
5. Now we have two simple equations:
1) 100%=9.137
2) x%=21.31
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%=9.137/21.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.31 is what percent of 9.137

100%/x%=9.137/21.31
(100/x)*x=(9.137/21.31)*x       - we multiply both sides of the equation by x
100=0.42876583763491*x       - we divide both sides of the equation by (0.42876583763491) to get x
100/0.42876583763491=x
233.2275363905=x
x=233.2275363905

now we have:
21.31 is 233.2275363905% of 9.137
