89 is what percent of 804 - 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 804 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 804, so we can write it down as 100%=804.
4. We know, that x% equals 89 of the output value, so we can write it down as x%=89.
5. Now we have two simple equations:
1) 100%=804
2) x%=89
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%=804/89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89 is what percent of 804

100%/x%=804/89
(100/x)*x=(804/89)*x       - we multiply both sides of the equation by x
100=9.0337078651685*x       - we divide both sides of the equation by (9.0337078651685) to get x
100/9.0337078651685=x
11.069651741294=x
x=11.069651741294

now we have:
89 is 11.069651741294% of 804
