89.85 is what percent of 209.65 - 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 209.65 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 209.65, so we can write it down as 100%=209.65.
4. We know, that x% equals 89.85 of the output value, so we can write it down as x%=89.85.
5. Now we have two simple equations:
1) 100%=209.65
2) x%=89.85
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%=209.65/89.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89.85 is what percent of 209.65

100%/x%=209.65/89.85
(100/x)*x=(209.65/89.85)*x       - we multiply both sides of the equation by x
100=2.3333333333333*x       - we divide both sides of the equation by (2.3333333333333) to get x
100/2.3333333333333=x
42.857142857143=x
x=42.857142857143

now we have:
89.85 is 42.857142857143% of 209.65
