209.55 is what percent of 412.5 - 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 412.5 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 412.5, so we can write it down as 100%=412.5.
4. We know, that x% equals 209.55 of the output value, so we can write it down as x%=209.55.
5. Now we have two simple equations:
1) 100%=412.5
2) x%=209.55
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%=412.5/209.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 209.55 is what percent of 412.5

100%/x%=412.5/209.55
(100/x)*x=(412.5/209.55)*x       - we multiply both sides of the equation by x
100=1.9685039370079*x       - we divide both sides of the equation by (1.9685039370079) to get x
100/1.9685039370079=x
50.8=x
x=50.8

now we have:
209.55 is 50.8% of 412.5
