11.42 is what percent of 3900 - 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 3900 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 3900, so we can write it down as 100%=3900.
4. We know, that x% equals 11.42 of the output value, so we can write it down as x%=11.42.
5. Now we have two simple equations:
1) 100%=3900
2) x%=11.42
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%=3900/11.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.42 is what percent of 3900

100%/x%=3900/11.42
(100/x)*x=(3900/11.42)*x       - we multiply both sides of the equation by x
100=341.5061295972*x       - we divide both sides of the equation by (341.5061295972) to get x
100/341.5061295972=x
0.29282051282051=x
x=0.29282051282051

now we have:
11.42 is 0.29282051282051% of 3900
