What is 48.8 percent of 8.72 - 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 8.72 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 8.72 is 100%, so we can write it down as 8.72=100%.
4. We know, that x is 48.8% of the output value, so we can write it down as x=48.8%.
5. Now we have two simple equations:
1) 8.72=100%
2) x=48.8%
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:
8.72/x=100%/48.8%
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 48.8% of 8.72

8.72/x=100/48.8
(8.72/x)*x=(100/48.8)*x       - we multiply both sides of the equation by x
8.72=2.0491803278689*x       - we divide both sides of the equation by (2.0491803278689) to get x
8.72/2.0491803278689=x
4.25536=x
x=4.25536

now we have:
48.8% of 8.72=4.25536
