387.5 is what percent of 441 - 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 441 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 441, so we can write it down as 100%=441.
4. We know, that x% equals 387.5 of the output value, so we can write it down as x%=387.5.
5. Now we have two simple equations:
1) 100%=441
2) x%=387.5
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%=441/387.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 387.5 is what percent of 441

100%/x%=441/387.5
(100/x)*x=(441/387.5)*x       - we multiply both sides of the equation by x
100=1.138064516129*x       - we divide both sides of the equation by (1.138064516129) to get x
100/1.138064516129=x
87.868480725624=x
x=87.868480725624

now we have:
387.5 is 87.868480725624% of 441
