0.34 is what percent of 0.39 - 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 0.39 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 100% equals 0.39, so we can write it down as 100%=0.39.
4. We know, that x% equals 0.34 of the output value, so we can write it down as x%=0.34.
5. Now we have two simple equations:
1) 100%=0.39
2) x%=0.34
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:
100%/x%=0.39/0.34
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.34 is what percent of 0.39

100%/x%=0.39/0.34
(100/x)*x=(0.39/0.34)*x       - we multiply both sides of the equation by x
100=1.1470588235294*x       - we divide both sides of the equation by (1.1470588235294) to get x
100/1.1470588235294=x
87.179487179487=x
x=87.179487179487

now we have:
0.34 is 87.179487179487% of 0.39
