What is 49 percent of 39.69 - 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 39.69 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 39.69 is 100%, so we can write it down as 39.69=100%.
4. We know, that x is 49% of the output value, so we can write it down as x=49%.
5. Now we have two simple equations:
1) 39.69=100%
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:
39.69/x=100%/49%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 49% of 39.69

39.69/x=100/49
(39.69/x)*x=(100/49)*x       - we multiply both sides of the equation by x
39.69=2.0408163265306*x       - we divide both sides of the equation by (2.0408163265306) to get x
39.69/2.0408163265306=x
19.4481=x
x=19.4481

now we have:
49% of 39.69=19.4481
