636.84 is what percent of 318.42 - 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 318.42 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 318.42, so we can write it down as 100%=318.42.
4. We know, that x% equals 636.84 of the output value, so we can write it down as x%=636.84.
5. Now we have two simple equations:
1) 100%=318.42
2) x%=636.84
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%=318.42/636.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 636.84 is what percent of 318.42

100%/x%=318.42/636.84
(100/x)*x=(318.42/636.84)*x       - we multiply both sides of the equation by x
100=0.5*x       - we divide both sides of the equation by (0.5) to get x
100/0.5=x
200=x
x=200

now we have:
636.84 is 200% of 318.42
