What is 9.7 percent of 13.1 - 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 13.1 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 13.1 is 100%, so we can write it down as 13.1=100%.
4. We know, that x is 9.7% of the output value, so we can write it down as x=9.7%.
5. Now we have two simple equations:
1) 13.1=100%
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:
13.1/x=100%/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 what is 9.7% of 13.1

13.1/x=100/9.7
(13.1/x)*x=(100/9.7)*x       - we multiply both sides of the equation by x
13.1=10.309278350515*x       - we divide both sides of the equation by (10.309278350515) to get x
13.1/10.309278350515=x
1.2707=x
x=1.2707

now we have:
9.7% of 13.1=1.2707
