What is 43.1 percent of 4.31 - 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 4.31 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 4.31 is 100%, so we can write it down as 4.31=100%.
4. We know, that x is 43.1% of the output value, so we can write it down as x=43.1%.
5. Now we have two simple equations:
1) 4.31=100%
2) x=43.1%
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:
4.31/x=100%/43.1%
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 43.1% of 4.31

4.31/x=100/43.1
(4.31/x)*x=(100/43.1)*x       - we multiply both sides of the equation by x
4.31=2.3201856148492*x       - we divide both sides of the equation by (2.3201856148492) to get x
4.31/2.3201856148492=x
1.85761=x
x=1.85761

now we have:
43.1% of 4.31=1.85761
