85 is what percent of 289.55 - 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 289.55 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 289.55, so we can write it down as 100%=289.55.
4. We know, that x% equals 85 of the output value, so we can write it down as x%=85.
5. Now we have two simple equations:
1) 100%=289.55
2) x%=85
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%=289.55/85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 85 is what percent of 289.55

100%/x%=289.55/85
(100/x)*x=(289.55/85)*x       - we multiply both sides of the equation by x
100=3.4064705882353*x       - we divide both sides of the equation by (3.4064705882353) to get x
100/3.4064705882353=x
29.355897081678=x
x=29.355897081678

now we have:
85 is 29.355897081678% of 289.55
