2.3 is what percent of 12.31 - 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 12.31 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 100% equals 12.31, so we can write it down as 100%=12.31.
4. We know, that x% equals 2.3 of the output value, so we can write it down as x%=2.3.
5. Now we have two simple equations:
1) 100%=12.31
2) x%=2.3
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:
100%/x%=12.31/2.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.3 is what percent of 12.31

100%/x%=12.31/2.3
(100/x)*x=(12.31/2.3)*x       - we multiply both sides of the equation by x
100=5.3521739130435*x       - we divide both sides of the equation by (5.3521739130435) to get x
100/5.3521739130435=x
18.683996750609=x
x=18.683996750609

now we have:
2.3 is 18.683996750609% of 12.31
