What is 49.75 percent of 39.8 - 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 39.8 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 39.8 is 100%, so we can write it down as 39.8=100%.
4. We know, that x is 49.75% of the output value, so we can write it down as x=49.75%.
5. Now we have two simple equations:
1) 39.8=100%
2) x=49.75%
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:
39.8/x=100%/49.75%
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 49.75% of 39.8

39.8/x=100/49.75
(39.8/x)*x=(100/49.75)*x       - we multiply both sides of the equation by x
39.8=2.0100502512563*x       - we divide both sides of the equation by (2.0100502512563) to get x
39.8/2.0100502512563=x
19.8005=x
x=19.8005

now we have:
49.75% of 39.8=19.8005
