109.15 is what percent of 250 - 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 250 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 250, so we can write it down as 100%=250.
4. We know, that x% equals 109.15 of the output value, so we can write it down as x%=109.15.
5. Now we have two simple equations:
1) 100%=250
2) x%=109.15
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%=250/109.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 109.15 is what percent of 250

100%/x%=250/109.15
(100/x)*x=(250/109.15)*x       - we multiply both sides of the equation by x
100=2.2904260192396*x       - we divide both sides of the equation by (2.2904260192396) to get x
100/2.2904260192396=x
43.66=x
x=43.66

now we have:
109.15 is 43.66% of 250
