12.99 is what percent of 32.99 - 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 32.99 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 32.99, so we can write it down as 100%=32.99.
4. We know, that x% equals 12.99 of the output value, so we can write it down as x%=12.99.
5. Now we have two simple equations:
1) 100%=32.99
2) x%=12.99
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%=32.99/12.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.99 is what percent of 32.99

100%/x%=32.99/12.99
(100/x)*x=(32.99/12.99)*x       - we multiply both sides of the equation by x
100=2.5396458814473*x       - we divide both sides of the equation by (2.5396458814473) to get x
100/2.5396458814473=x
39.375568354047=x
x=39.375568354047

now we have:
12.99 is 39.375568354047% of 32.99
