8.1 is what percent of 32.3 - 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 32.3 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 32.3, so we can write it down as 100%=32.3.
4. We know, that x% equals 8.1 of the output value, so we can write it down as x%=8.1.
5. Now we have two simple equations:
1) 100%=32.3
2) x%=8.1
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%=32.3/8.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.1 is what percent of 32.3

100%/x%=32.3/8.1
(100/x)*x=(32.3/8.1)*x       - we multiply both sides of the equation by x
100=3.98765432099*x       - we divide both sides of the equation by (3.98765432099) to get x
100/3.98765432099=x
25.0773993808=x
x=25.0773993808

now we have:
8.1 is 25.0773993808% of 32.3
