What is 25.01 percent of 19.99 - 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 19.99 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 19.99 is 100%, so we can write it down as 19.99=100%.
4. We know, that x is 25.01% of the output value, so we can write it down as x=25.01%.
5. Now we have two simple equations:
1) 19.99=100%
2) x=25.01%
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:
19.99/x=100%/25.01%
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 25.01% of 19.99

19.99/x=100/25.01
(19.99/x)*x=(100/25.01)*x       - we multiply both sides of the equation by x
19.99=3.9984006397441*x       - we divide both sides of the equation by (3.9984006397441) to get x
19.99/3.9984006397441=x
4.999499=x
x=4.999499

now we have:
25.01% of 19.99=4.999499
