3.9 is what percent of 95 - 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 95 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 95, so we can write it down as 100%=95.
4. We know, that x% equals 3.9 of the output value, so we can write it down as x%=3.9.
5. Now we have two simple equations:
1) 100%=95
2) x%=3.9
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%=95/3.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.9 is what percent of 95

100%/x%=95/3.9
(100/x)*x=(95/3.9)*x       - we multiply both sides of the equation by x
100=24.358974358974*x       - we divide both sides of the equation by (24.358974358974) to get x
100/24.358974358974=x
4.1052631578947=x
x=4.1052631578947

now we have:
3.9 is 4.1052631578947% of 95
