What is 69.4 percent of 12.5 - 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 12.5 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 12.5 is 100%, so we can write it down as 12.5=100%.
4. We know, that x is 69.4% of the output value, so we can write it down as x=69.4%.
5. Now we have two simple equations:
1) 12.5=100%
2) x=69.4%
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:
12.5/x=100%/69.4%
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 69.4% of 12.5

12.5/x=100/69.4
(12.5/x)*x=(100/69.4)*x       - we multiply both sides of the equation by x
12.5=1.4409221902017*x       - we divide both sides of the equation by (1.4409221902017) to get x
12.5/1.4409221902017=x
8.675=x
x=8.675

now we have:
69.4% of 12.5=8.675
