23.8 is what percent of 199.9 - 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 199.9 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 199.9, so we can write it down as 100%=199.9.
4. We know, that x% equals 23.8 of the output value, so we can write it down as x%=23.8.
5. Now we have two simple equations:
1) 100%=199.9
2) x%=23.8
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%=199.9/23.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 23.8 is what percent of 199.9

100%/x%=199.9/23.8
(100/x)*x=(199.9/23.8)*x       - we multiply both sides of the equation by x
100=8.3991596638655*x       - we divide both sides of the equation by (8.3991596638655) to get x
100/8.3991596638655=x
11.905952976488=x
x=11.905952976488

now we have:
23.8 is 11.905952976488% of 199.9
