What is 0.875 percent of 28 - 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 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 is 100%, so we can write it down as 28=100%.
4. We know, that x is 0.875% of the output value, so we can write it down as x=0.875%.
5. Now we have two simple equations:
1) 28=100%
2) x=0.875%
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/x=100%/0.875%
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 0.875% of 28

28/x=100/0.875
(28/x)*x=(100/0.875)*x       - we multiply both sides of the equation by x
28=114.28571428571*x       - we divide both sides of the equation by (114.28571428571) to get x
28/114.28571428571=x
0.245=x
x=0.245

now we have:
0.875% of 28=0.245
