17.25 is what percent of 123.99 - 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 123.99 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 123.99, so we can write it down as 100%=123.99.
4. We know, that x% equals 17.25 of the output value, so we can write it down as x%=17.25.
5. Now we have two simple equations:
1) 100%=123.99
2) x%=17.25
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%=123.99/17.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.25 is what percent of 123.99

100%/x%=123.99/17.25
(100/x)*x=(123.99/17.25)*x       - we multiply both sides of the equation by x
100=7.1878260869565*x       - we divide both sides of the equation by (7.1878260869565) to get x
100/7.1878260869565=x
13.912412291314=x
x=13.912412291314

now we have:
17.25 is 13.912412291314% of 123.99
