3.85 is what percent of 30.05 - 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 30.05 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 30.05, so we can write it down as 100%=30.05.
4. We know, that x% equals 3.85 of the output value, so we can write it down as x%=3.85.
5. Now we have two simple equations:
1) 100%=30.05
2) x%=3.85
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%=30.05/3.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.85 is what percent of 30.05

100%/x%=30.05/3.85
(100/x)*x=(30.05/3.85)*x       - we multiply both sides of the equation by x
100=7.8051948051948*x       - we divide both sides of the equation by (7.8051948051948) to get x
100/7.8051948051948=x
12.811980033278=x
x=12.811980033278

now we have:
3.85 is 12.811980033278% of 30.05
