What is 0.86 percent of 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 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 4 is 100%, so we can write it down as 4=100%.
4. We know, that x is 0.86% of the output value, so we can write it down as x=0.86%.
5. Now we have two simple equations:
1) 4=100%
2) x=0.86%
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:
4/x=100%/0.86%
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 0.86% of 4

4/x=100/0.86
(4/x)*x=(100/0.86)*x       - we multiply both sides of the equation by x
4=116.27906976744*x       - we divide both sides of the equation by (116.27906976744) to get x
4/116.27906976744=x
0.0344=x
x=0.0344

now we have:
0.86% of 4=0.0344
