What is 100 percent of 0.39 - 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 0.39 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 0.39 is 100%, so we can write it down as 0.39=100%.
4. We know, that x is 100% of the output value, so we can write it down as x=100%.
5. Now we have two simple equations:
1) 0.39=100%
2) x=100%
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:
0.39/x=100%/100%
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 100% of 0.39

0.39/x=100/100
(0.39/x)*x=(100/100)*x       - we multiply both sides of the equation by x
0.39=1*x       - we divide both sides of the equation by (1) to get x
0.39/1=x
0.39=x
x=0.39

now we have:
100% of 0.39=0.39
