15.19 is what percent of 171.15 - 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 171.15 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 171.15, so we can write it down as 100%=171.15.
4. We know, that x% equals 15.19 of the output value, so we can write it down as x%=15.19.
5. Now we have two simple equations:
1) 100%=171.15
2) x%=15.19
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%=171.15/15.19
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.19 is what percent of 171.15

100%/x%=171.15/15.19
(100/x)*x=(171.15/15.19)*x       - we multiply both sides of the equation by x
100=11.267281105991*x       - we divide both sides of the equation by (11.267281105991) to get x
100/11.267281105991=x
8.8752556237219=x
x=8.8752556237219

now we have:
15.19 is 8.8752556237219% of 171.15
