12.15 is what percent of 27.75 - 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 27.75 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 27.75, so we can write it down as 100%=27.75.
4. We know, that x% equals 12.15 of the output value, so we can write it down as x%=12.15.
5. Now we have two simple equations:
1) 100%=27.75
2) x%=12.15
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%=27.75/12.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.15 is what percent of 27.75

100%/x%=27.75/12.15
(100/x)*x=(27.75/12.15)*x       - we multiply both sides of the equation by x
100=2.283950617284*x       - we divide both sides of the equation by (2.283950617284) to get x
100/2.283950617284=x
43.783783783784=x
x=43.783783783784

now we have:
12.15 is 43.783783783784% of 27.75
