What is 63.1 percent of 684 - 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 684 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 684 is 100%, so we can write it down as 684=100%.
4. We know, that x is 63.1% of the output value, so we can write it down as x=63.1%.
5. Now we have two simple equations:
1) 684=100%
2) x=63.1%
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:
684/x=100%/63.1%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 63.1% of 684

684/x=100/63.1
(684/x)*x=(100/63.1)*x       - we multiply both sides of the equation by x
684=1.5847860538827*x       - we divide both sides of the equation by (1.5847860538827) to get x
684/1.5847860538827=x
431.604=x
x=431.604

now we have:
63.1% of 684=431.604
