What is 4.28 percent of 3.14 - 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 3.14 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 3.14 is 100%, so we can write it down as 3.14=100%.
4. We know, that x is 4.28% of the output value, so we can write it down as x=4.28%.
5. Now we have two simple equations:
1) 3.14=100%
2) x=4.28%
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:
3.14/x=100%/4.28%
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 4.28% of 3.14

3.14/x=100/4.28
(3.14/x)*x=(100/4.28)*x       - we multiply both sides of the equation by x
3.14=23.364485981308*x       - we divide both sides of the equation by (23.364485981308) to get x
3.14/23.364485981308=x
0.134392=x
x=0.134392

now we have:
4.28% of 3.14=0.134392
