83 is what percent of 839 - 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 839 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 839, so we can write it down as 100%=839.
4. We know, that x% equals 83 of the output value, so we can write it down as x%=83.
5. Now we have two simple equations:
1) 100%=839
2) x%=83
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%=839/83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 83 is what percent of 839

100%/x%=839/83
(100/x)*x=(839/83)*x       - we multiply both sides of the equation by x
100=10.10843373494*x       - we divide both sides of the equation by (10.10843373494) to get x
100/10.10843373494=x
9.8927294398093=x
x=9.8927294398093

now we have:
83 is 9.8927294398093% of 839
