111.5 is what percent of 289.99 - 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 289.99 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 289.99, so we can write it down as 100%=289.99.
4. We know, that x% equals 111.5 of the output value, so we can write it down as x%=111.5.
5. Now we have two simple equations:
1) 100%=289.99
2) x%=111.5
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%=289.99/111.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 111.5 is what percent of 289.99

100%/x%=289.99/111.5
(100/x)*x=(289.99/111.5)*x       - we multiply both sides of the equation by x
100=2.6008071748879*x       - we divide both sides of the equation by (2.6008071748879) to get x
100/2.6008071748879=x
38.449601710404=x
x=38.449601710404

now we have:
111.5 is 38.449601710404% of 289.99
