809.22 is what percent of 878 - 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 878 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 878, so we can write it down as 100%=878.
4. We know, that x% equals 809.22 of the output value, so we can write it down as x%=809.22.
5. Now we have two simple equations:
1) 100%=878
2) x%=809.22
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%=878/809.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 809.22 is what percent of 878

100%/x%=878/809.22
(100/x)*x=(878/809.22)*x       - we multiply both sides of the equation by x
100=1.0849954276958*x       - we divide both sides of the equation by (1.0849954276958) to get x
100/1.0849954276958=x
92.166287015945=x
x=92.166287015945

now we have:
809.22 is 92.166287015945% of 878
