23 is what percent of 8.5 - 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 8.5 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 8.5, so we can write it down as 100%=8.5.
4. We know, that x% equals 23 of the output value, so we can write it down as x%=23.
5. Now we have two simple equations:
1) 100%=8.5
2) x%=23
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%=8.5/23
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 23 is what percent of 8.5

100%/x%=8.5/23
(100/x)*x=(8.5/23)*x       - we multiply both sides of the equation by x
100=0.3695652173913*x       - we divide both sides of the equation by (0.3695652173913) to get x
100/0.3695652173913=x
270.58823529412=x
x=270.58823529412

now we have:
23 is 270.58823529412% of 8.5
