109.89 is what percent of 2500 - 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 2500 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 2500, so we can write it down as 100%=2500.
4. We know, that x% equals 109.89 of the output value, so we can write it down as x%=109.89.
5. Now we have two simple equations:
1) 100%=2500
2) x%=109.89
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%=2500/109.89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 109.89 is what percent of 2500

100%/x%=2500/109.89
(100/x)*x=(2500/109.89)*x       - we multiply both sides of the equation by x
100=22.750022750023*x       - we divide both sides of the equation by (22.750022750023) to get x
100/22.750022750023=x
4.3956=x
x=4.3956

now we have:
109.89 is 4.3956% of 2500
