209.1 is what percent of 1242.73 - 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 1242.73 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 1242.73, so we can write it down as 100%=1242.73.
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%=1242.73
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%=1242.73/209.1
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 1242.73

100%/x%=1242.73/209.1
(100/x)*x=(1242.73/209.1)*x       - we multiply both sides of the equation by x
100=5.9432329029173*x       - we divide both sides of the equation by (5.9432329029173) to get x
100/5.9432329029173=x
16.82585919709=x
x=16.82585919709

now we have:
209.1 is 16.82585919709% of 1242.73
