What is 0.25 percent of 20.997 - 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 20.997 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 20.997 is 100%, so we can write it down as 20.997=100%.
4. We know, that x is 0.25% of the output value, so we can write it down as x=0.25%.
5. Now we have two simple equations:
1) 20.997=100%
2) x=0.25%
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:
20.997/x=100%/0.25%
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 0.25% of 20.997

20.997/x=100/0.25
(20.997/x)*x=(100/0.25)*x       - we multiply both sides of the equation by x
20.997=400*x       - we divide both sides of the equation by (400) to get x
20.997/400=x
0.0524925=x
x=0.0524925

now we have:
0.25% of 20.997=0.0524925
