What is 39.4 percent of 69 - 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 69 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 69 is 100%, so we can write it down as 69=100%.
4. We know, that x is 39.4% of the output value, so we can write it down as x=39.4%.
5. Now we have two simple equations:
1) 69=100%
2) x=39.4%
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:
69/x=100%/39.4%
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 39.4% of 69

69/x=100/39.4
(69/x)*x=(100/39.4)*x       - we multiply both sides of the equation by x
69=2.5380710659898*x       - we divide both sides of the equation by (2.5380710659898) to get x
69/2.5380710659898=x
27.186=x
x=27.186

now we have:
39.4% of 69=27.186
