635.5 is what percent of 1004.5 - 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 1004.5 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 1004.5, so we can write it down as 100%=1004.5.
4. We know, that x% equals 635.5 of the output value, so we can write it down as x%=635.5.
5. Now we have two simple equations:
1) 100%=1004.5
2) x%=635.5
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%=1004.5/635.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 635.5 is what percent of 1004.5

100%/x%=1004.5/635.5
(100/x)*x=(1004.5/635.5)*x       - we multiply both sides of the equation by x
100=1.5806451612903*x       - we divide both sides of the equation by (1.5806451612903) to get x
100/1.5806451612903=x
63.265306122449=x
x=63.265306122449

now we have:
635.5 is 63.265306122449% of 1004.5
