439.73 is what percent of 630 - 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 630 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 630, so we can write it down as 100%=630.
4. We know, that x% equals 439.73 of the output value, so we can write it down as x%=439.73.
5. Now we have two simple equations:
1) 100%=630
2) x%=439.73
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%=630/439.73
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 439.73 is what percent of 630

100%/x%=630/439.73
(100/x)*x=(630/439.73)*x       - we multiply both sides of the equation by x
100=1.4326973370023*x       - we divide both sides of the equation by (1.4326973370023) to get x
100/1.4326973370023=x
69.798412698413=x
x=69.798412698413

now we have:
439.73 is 69.798412698413% of 630
