What is 130 percent of 10.31 - 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 10.31 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 10.31 is 100%, so we can write it down as 10.31=100%.
4. We know, that x is 130% of the output value, so we can write it down as x=130%.
5. Now we have two simple equations:
1) 10.31=100%
2) x=130%
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:
10.31/x=100%/130%
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 130% of 10.31

10.31/x=100/130
(10.31/x)*x=(100/130)*x       - we multiply both sides of the equation by x
10.31=0.76923076923077*x       - we divide both sides of the equation by (0.76923076923077) to get x
10.31/0.76923076923077=x
13.403=x
x=13.403

now we have:
130% of 10.31=13.403
