9.3 is what percent of 12.8 - 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 12.8 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 12.8, so we can write it down as 100%=12.8.
4. We know, that x% equals 9.3 of the output value, so we can write it down as x%=9.3.
5. Now we have two simple equations:
1) 100%=12.8
2) x%=9.3
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%=12.8/9.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.3 is what percent of 12.8

100%/x%=12.8/9.3
(100/x)*x=(12.8/9.3)*x       - we multiply both sides of the equation by x
100=1.3763440860215*x       - we divide both sides of the equation by (1.3763440860215) to get x
100/1.3763440860215=x
72.65625=x
x=72.65625

now we have:
9.3 is 72.65625% of 12.8
