17.09 is what percent of 18.99 - 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 18.99 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 18.99, so we can write it down as 100%=18.99.
4. We know, that x% equals 17.09 of the output value, so we can write it down as x%=17.09.
5. Now we have two simple equations:
1) 100%=18.99
2) x%=17.09
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%=18.99/17.09
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.09 is what percent of 18.99

100%/x%=18.99/17.09
(100/x)*x=(18.99/17.09)*x       - we multiply both sides of the equation by x
100=1.1111761263897*x       - we divide both sides of the equation by (1.1111761263897) to get x
100/1.1111761263897=x
89.994734070563=x
x=89.994734070563

now we have:
17.09 is 89.994734070563% of 18.99
