13.31 is what percent of 149.99 - 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 149.99 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 149.99, so we can write it down as 100%=149.99.
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%=149.99
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%=149.99/13.31
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 149.99

100%/x%=149.99/13.31
(100/x)*x=(149.99/13.31)*x       - we multiply both sides of the equation by x
100=11.268970698723*x       - we divide both sides of the equation by (11.268970698723) to get x
100/11.268970698723=x
8.8739249283286=x
x=8.8739249283286

now we have:
13.31 is 8.8739249283286% of 149.99
