What is 139.99 percent of 0.4 - 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 0.4 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 0.4 is 100%, so we can write it down as 0.4=100%.
4. We know, that x is 139.99% of the output value, so we can write it down as x=139.99%.
5. Now we have two simple equations:
1) 0.4=100%
2) x=139.99%
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:
0.4/x=100%/139.99%
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 139.99% of 0.4

0.4/x=100/139.99
(0.4/x)*x=(100/139.99)*x       - we multiply both sides of the equation by x
0.4=0.71433673833845*x       - we divide both sides of the equation by (0.71433673833845) to get x
0.4/0.71433673833845=x
0.55996=x
x=0.55996

now we have:
139.99% of 0.4=0.55996
