What is 2.31 percent of 39 - 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 39 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 39 is 100%, so we can write it down as 39=100%.
4. We know, that x is 2.31% of the output value, so we can write it down as x=2.31%.
5. Now we have two simple equations:
1) 39=100%
2) x=2.31%
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:
39/x=100%/2.31%
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 2.31% of 39

39/x=100/2.31
(39/x)*x=(100/2.31)*x       - we multiply both sides of the equation by x
39=43.290043290043*x       - we divide both sides of the equation by (43.290043290043) to get x
39/43.290043290043=x
0.9009=x
x=0.9009

now we have:
2.31% of 39=0.9009
