What is 34 percent of 129.2 - 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 129.2 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 129.2 is 100%, so we can write it down as 129.2=100%.
4. We know, that x is 34% of the output value, so we can write it down as x=34%.
5. Now we have two simple equations:
1) 129.2=100%
2) x=34%
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:
129.2/x=100%/34%
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 34% of 129.2

129.2/x=100/34
(129.2/x)*x=(100/34)*x       - we multiply both sides of the equation by x
129.2=2.94117647059*x       - we divide both sides of the equation by (2.94117647059) to get x
129.2/2.94117647059=x
43.928=x
x=43.928

now we have:
34% of 129.2=43.928
