1278.24 is what percent of 3240 - 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 3240 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 3240, so we can write it down as 100%=3240.
4. We know, that x% equals 1278.24 of the output value, so we can write it down as x%=1278.24.
5. Now we have two simple equations:
1) 100%=3240
2) x%=1278.24
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%=3240/1278.24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1278.24 is what percent of 3240

100%/x%=3240/1278.24
(100/x)*x=(3240/1278.24)*x       - we multiply both sides of the equation by x
100=2.5347352609839*x       - we divide both sides of the equation by (2.5347352609839) to get x
100/2.5347352609839=x
39.451851851852=x
x=39.451851851852

now we have:
1278.24 is 39.451851851852% of 3240
