578.8 is what percent of 824 - 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 824 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 824, so we can write it down as 100%=824.
4. We know, that x% equals 578.8 of the output value, so we can write it down as x%=578.8.
5. Now we have two simple equations:
1) 100%=824
2) x%=578.8
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%=824/578.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 578.8 is what percent of 824

100%/x%=824/578.8
(100/x)*x=(824/578.8)*x       - we multiply both sides of the equation by x
100=1.4236351071182*x       - we divide both sides of the equation by (1.4236351071182) to get x
100/1.4236351071182=x
70.242718446602=x
x=70.242718446602

now we have:
578.8 is 70.242718446602% of 824
