822.18 is what percent of 579 - 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 579 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 579, so we can write it down as 100%=579.
4. We know, that x% equals 822.18 of the output value, so we can write it down as x%=822.18.
5. Now we have two simple equations:
1) 100%=579
2) x%=822.18
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%=579/822.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 822.18 is what percent of 579

100%/x%=579/822.18
(100/x)*x=(579/822.18)*x       - we multiply both sides of the equation by x
100=0.70422535211268*x       - we divide both sides of the equation by (0.70422535211268) to get x
100/0.70422535211268=x
142=x
x=142

now we have:
822.18 is 142% of 579
