8.1 is what percent of 23.8 - 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 23.8 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 23.8, so we can write it down as 100%=23.8.
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%=23.8
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%=23.8/8.1
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 23.8

100%/x%=23.8/8.1
(100/x)*x=(23.8/8.1)*x       - we multiply both sides of the equation by x
100=2.9382716049383*x       - we divide both sides of the equation by (2.9382716049383) to get x
100/2.9382716049383=x
34.033613445378=x
x=34.033613445378

now we have:
8.1 is 34.033613445378% of 23.8
