207.2 is what percent of 403.2 - 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 403.2 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 403.2, so we can write it down as 100%=403.2.
4. We know, that x% equals 207.2 of the output value, so we can write it down as x%=207.2.
5. Now we have two simple equations:
1) 100%=403.2
2) x%=207.2
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%=403.2/207.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 207.2 is what percent of 403.2

100%/x%=403.2/207.2
(100/x)*x=(403.2/207.2)*x       - we multiply both sides of the equation by x
100=1.9459459459459*x       - we divide both sides of the equation by (1.9459459459459) to get x
100/1.9459459459459=x
51.388888888889=x
x=51.388888888889

now we have:
207.2 is 51.388888888889% of 403.2
