49 is what percent of 439 - 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 439 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 439, so we can write it down as 100%=439.
4. We know, that x% equals 49 of the output value, so we can write it down as x%=49.
5. Now we have two simple equations:
1) 100%=439
2) x%=49
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%=439/49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49 is what percent of 439

100%/x%=439/49
(100/x)*x=(439/49)*x       - we multiply both sides of the equation by x
100=8.9591836734694*x       - we divide both sides of the equation by (8.9591836734694) to get x
100/8.9591836734694=x
11.161731207289=x
x=11.161731207289

now we have:
49 is 11.161731207289% of 439
