209.1 is what percent of 897.1 - 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 897.1 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 897.1, so we can write it down as 100%=897.1.
4. We know, that x% equals 209.1 of the output value, so we can write it down as x%=209.1.
5. Now we have two simple equations:
1) 100%=897.1
2) x%=209.1
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%=897.1/209.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 209.1 is what percent of 897.1

100%/x%=897.1/209.1
(100/x)*x=(897.1/209.1)*x       - we multiply both sides of the equation by x
100=4.29029172645*x       - we divide both sides of the equation by (4.29029172645) to get x
100/4.29029172645=x
23.3084383012=x
x=23.3084383012

now we have:
209.1 is 23.3084383012% of 897.1
