397.56 is what percent of 50400 - 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 50400 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 50400, so we can write it down as 100%=50400.
4. We know, that x% equals 397.56 of the output value, so we can write it down as x%=397.56.
5. Now we have two simple equations:
1) 100%=50400
2) x%=397.56
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%=50400/397.56
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 397.56 is what percent of 50400

100%/x%=50400/397.56
(100/x)*x=(50400/397.56)*x       - we multiply both sides of the equation by x
100=126.77331723513*x       - we divide both sides of the equation by (126.77331723513) to get x
100/126.77331723513=x
0.78880952380952=x
x=0.78880952380952

now we have:
397.56 is 0.78880952380952% of 50400
