What is 28.125 percent of 4.5 - 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 4.5 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 4.5 is 100%, so we can write it down as 4.5=100%.
4. We know, that x is 28.125% of the output value, so we can write it down as x=28.125%.
5. Now we have two simple equations:
1) 4.5=100%
2) x=28.125%
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:
4.5/x=100%/28.125%
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 28.125% of 4.5

4.5/x=100/28.125
(4.5/x)*x=(100/28.125)*x       - we multiply both sides of the equation by x
4.5=3.5555555555556*x       - we divide both sides of the equation by (3.5555555555556) to get x
4.5/3.5555555555556=x
1.265625=x
x=1.265625

now we have:
28.125% of 4.5=1.265625
