83 is what percent of 823 - 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 823 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 823, so we can write it down as 100%=823.
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%=823
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%=823/83
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 823

100%/x%=823/83
(100/x)*x=(823/83)*x       - we multiply both sides of the equation by x
100=9.9156626506024*x       - we divide both sides of the equation by (9.9156626506024) to get x
100/9.9156626506024=x
10.085054678007=x
x=10.085054678007

now we have:
83 is 10.085054678007% of 823
