What is 21.375 percent of 28.5 - 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 28.5 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 28.5 is 100%, so we can write it down as 28.5=100%.
4. We know, that x is 21.375% of the output value, so we can write it down as x=21.375%.
5. Now we have two simple equations:
1) 28.5=100%
2) x=21.375%
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:
28.5/x=100%/21.375%
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 21.375% of 28.5

28.5/x=100/21.375
(28.5/x)*x=(100/21.375)*x       - we multiply both sides of the equation by x
28.5=4.6783625730994*x       - we divide both sides of the equation by (4.6783625730994) to get x
28.5/4.6783625730994=x
6.091875=x
x=6.091875

now we have:
21.375% of 28.5=6.091875
