3.39 is what percent of 129 - 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 129 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 129, so we can write it down as 100%=129.
4. We know, that x% equals 3.39 of the output value, so we can write it down as x%=3.39.
5. Now we have two simple equations:
1) 100%=129
2) x%=3.39
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%=129/3.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.39 is what percent of 129

100%/x%=129/3.39
(100/x)*x=(129/3.39)*x       - we multiply both sides of the equation by x
100=38.053097345133*x       - we divide both sides of the equation by (38.053097345133) to get x
100/38.053097345133=x
2.6279069767442=x
x=2.6279069767442

now we have:
3.39 is 2.6279069767442% of 129
