13.31 is what percent of 10 - 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 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 10, so we can write it down as 100%=10.
4. We know, that x% equals 13.31 of the output value, so we can write it down as x%=13.31.
5. Now we have two simple equations:
1) 100%=10
2) x%=13.31
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%=10/13.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.31 is what percent of 10

100%/x%=10/13.31
(100/x)*x=(10/13.31)*x       - we multiply both sides of the equation by x
100=0.75131480090158*x       - we divide both sides of the equation by (0.75131480090158) to get x
100/0.75131480090158=x
133.1=x
x=133.1

now we have:
13.31 is 133.1% of 10
