9.7 is what percent of 15.31 - 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 15.31 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 15.31, so we can write it down as 100%=15.31.
4. We know, that x% equals 9.7 of the output value, so we can write it down as x%=9.7.
5. Now we have two simple equations:
1) 100%=15.31
2) x%=9.7
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%=15.31/9.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.7 is what percent of 15.31

100%/x%=15.31/9.7
(100/x)*x=(15.31/9.7)*x       - we multiply both sides of the equation by x
100=1.5783505154639*x       - we divide both sides of the equation by (1.5783505154639) to get x
100/1.5783505154639=x
63.357282821685=x
x=63.357282821685

now we have:
9.7 is 63.357282821685% of 15.31
