8.9 is what percent of 328.2 - 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 328.2 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 328.2, so we can write it down as 100%=328.2.
4. We know, that x% equals 8.9 of the output value, so we can write it down as x%=8.9.
5. Now we have two simple equations:
1) 100%=328.2
2) x%=8.9
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%=328.2/8.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.9 is what percent of 328.2

100%/x%=328.2/8.9
(100/x)*x=(328.2/8.9)*x       - we multiply both sides of the equation by x
100=36.876404494382*x       - we divide both sides of the equation by (36.876404494382) to get x
100/36.876404494382=x
2.7117611212675=x
x=2.7117611212675

now we have:
8.9 is 2.7117611212675% of 328.2
