84.5 is what percent of 89 - 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 89 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 89, so we can write it down as 100%=89.
4. We know, that x% equals 84.5 of the output value, so we can write it down as x%=84.5.
5. Now we have two simple equations:
1) 100%=89
2) x%=84.5
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%=89/84.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 84.5 is what percent of 89

100%/x%=89/84.5
(100/x)*x=(89/84.5)*x       - we multiply both sides of the equation by x
100=1.0532544378698*x       - we divide both sides of the equation by (1.0532544378698) to get x
100/1.0532544378698=x
94.943820224719=x
x=94.943820224719

now we have:
84.5 is 94.943820224719% of 89
