172.79 is what percent of 691.17 - 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 691.17 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 691.17, so we can write it down as 100%=691.17.
4. We know, that x% equals 172.79 of the output value, so we can write it down as x%=172.79.
5. Now we have two simple equations:
1) 100%=691.17
2) x%=172.79
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%=691.17/172.79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 172.79 is what percent of 691.17

100%/x%=691.17/172.79
(100/x)*x=(691.17/172.79)*x       - we multiply both sides of the equation by x
100=4.0000578737195*x       - we divide both sides of the equation by (4.0000578737195) to get x
100/4.0000578737195=x
24.999638294486=x
x=24.999638294486

now we have:
