616.32 is what percent of 856 - 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 856 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 856, so we can write it down as 100%=856.
4. We know, that x% equals 616.32 of the output value, so we can write it down as x%=616.32.
5. Now we have two simple equations:
1) 100%=856
2) x%=616.32
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%=856/616.32
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 616.32 is what percent of 856

100%/x%=856/616.32
(100/x)*x=(856/616.32)*x       - we multiply both sides of the equation by x
100=1.3888888888889*x       - we divide both sides of the equation by (1.3888888888889) to get x
100/1.3888888888889=x
72=x
x=72

now we have:
616.32 is 72% of 856
