What is 19.09 percent of 25.45 - 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 25.45 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 25.45 is 100%, so we can write it down as 25.45=100%.
4. We know, that x is 19.09% of the output value, so we can write it down as x=19.09%.
5. Now we have two simple equations:
1) 25.45=100%
2) x=19.09%
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:
25.45/x=100%/19.09%
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 19.09% of 25.45

25.45/x=100/19.09
(25.45/x)*x=(100/19.09)*x       - we multiply both sides of the equation by x
25.45=5.2383446830801*x       - we divide both sides of the equation by (5.2383446830801) to get x
25.45/5.2383446830801=x
4.858405=x
x=4.858405

now we have:
19.09% of 25.45=4.858405
