13.99 is what percent of 15.75 - 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 15.75 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 15.75, so we can write it down as 100%=15.75.
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%=15.75
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%=15.75/13.99
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 15.75

100%/x%=15.75/13.99
(100/x)*x=(15.75/13.99)*x       - we multiply both sides of the equation by x
100=1.1258041458184*x       - we divide both sides of the equation by (1.1258041458184) to get x
100/1.1258041458184=x
88.825396825397=x
x=88.825396825397

now we have:
13.99 is 88.825396825397% of 15.75
