What is 52 percent of 3.9 - 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 3.9 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 3.9 is 100%, so we can write it down as 3.9=100%.
4. We know, that x is 52% of the output value, so we can write it down as x=52%.
5. Now we have two simple equations:
1) 3.9=100%
2) x=52%
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:
3.9/x=100%/52%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 52% of 3.9

3.9/x=100/52
(3.9/x)*x=(100/52)*x       - we multiply both sides of the equation by x
3.9=1.9230769230769*x       - we divide both sides of the equation by (1.9230769230769) to get x
3.9/1.9230769230769=x
2.028=x
x=2.028

now we have:
52% of 3.9=2.028
