612.27 is what percent of 3942.4 - 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 3942.4 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 3942.4, so we can write it down as 100%=3942.4.
4. We know, that x% equals 612.27 of the output value, so we can write it down as x%=612.27.
5. Now we have two simple equations:
1) 100%=3942.4
2) x%=612.27
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%=3942.4/612.27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 612.27 is what percent of 3942.4

100%/x%=3942.4/612.27
(100/x)*x=(3942.4/612.27)*x       - we multiply both sides of the equation by x
100=6.4389893347706*x       - we divide both sides of the equation by (6.4389893347706) to get x
100/6.4389893347706=x
15.530387581169=x
x=15.530387581169

now we have:
