What is 0.39 percent of 0.43 - 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 0.43 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 0.43 is 100%, so we can write it down as 0.43=100%.
4. We know, that x is 0.39% of the output value, so we can write it down as x=0.39%.
5. Now we have two simple equations:
1) 0.43=100%
2) x=0.39%
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:
0.43/x=100%/0.39%
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 0.39% of 0.43

0.43/x=100/0.39
(0.43/x)*x=(100/0.39)*x       - we multiply both sides of the equation by x
0.43=256.41025641026*x       - we divide both sides of the equation by (256.41025641026) to get x
0.43/256.41025641026=x
0.001677=x
x=0.001677

now we have:
0.39% of 0.43=0.001677
