12.95 is what percent of 40.5 - 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 40.5 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 100% equals 40.5, so we can write it down as 100%=40.5.
4. We know, that x% equals 12.95 of the output value, so we can write it down as x%=12.95.
5. Now we have two simple equations:
1) 100%=40.5
2) x%=12.95
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%=40.5/12.95
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.95 is what percent of 40.5

100%/x%=40.5/12.95
(100/x)*x=(40.5/12.95)*x       - we multiply both sides of the equation by x
100=3.1274131274131*x       - we divide both sides of the equation by (3.1274131274131) to get x
100/3.1274131274131=x
31.975308641975=x
x=31.975308641975

now we have:
12.95 is 31.975308641975% of 40.5
