13.99 is what percent of 15.65 - 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 15.65 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 15.65, so we can write it down as 100%=15.65.
4. We know, that x% equals 13.99 of the output value, so we can write it down as x%=13.99.
5. Now we have two simple equations:
1) 100%=15.65
2) x%=13.99
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%=15.65/13.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.99 is what percent of 15.65

100%/x%=15.65/13.99
(100/x)*x=(15.65/13.99)*x       - we multiply both sides of the equation by x
100=1.1186561829878*x       - we divide both sides of the equation by (1.1186561829878) to get x
100/1.1186561829878=x
89.392971246006=x
x=89.392971246006

now we have:
13.99 is 89.392971246006% of 15.65
