15.19 is what percent of 685.59 - 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 685.59 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 685.59, so we can write it down as 100%=685.59.
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%=685.59
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%=685.59/15.19
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 685.59

100%/x%=685.59/15.19
(100/x)*x=(685.59/15.19)*x       - we multiply both sides of the equation by x
100=45.134298880843*x       - we divide both sides of the equation by (45.134298880843) to get x
100/45.134298880843=x
2.21560991263=x
x=2.21560991263

now we have:
15.19 is 2.21560991263% of 685.59
