What is 1.25 percent of 728 - 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 728 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 728 is 100%, so we can write it down as 728=100%.
4. We know, that x is 1.25% of the output value, so we can write it down as x=1.25%.
5. Now we have two simple equations:
1) 728=100%
2) x=1.25%
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:
728/x=100%/1.25%
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 1.25% of 728

728/x=100/1.25
(728/x)*x=(100/1.25)*x       - we multiply both sides of the equation by x
728=80*x       - we divide both sides of the equation by (80) to get x
728/80=x
9.1=x
x=9.1

now we have:
1.25% of 728=9.1
