646.4 is what percent of 1082 - 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 1082 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 1082, so we can write it down as 100%=1082.
4. We know, that x% equals 646.4 of the output value, so we can write it down as x%=646.4.
5. Now we have two simple equations:
1) 100%=1082
2) x%=646.4
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%=1082/646.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 646.4 is what percent of 1082

100%/x%=1082/646.4
(100/x)*x=(1082/646.4)*x       - we multiply both sides of the equation by x
100=1.67388613861*x       - we divide both sides of the equation by (1.67388613861) to get x
100/1.67388613861=x
59.741219963=x
x=59.741219963

now we have:
646.4 is 59.741219963% of 1082
