What is 8.72 percent of 64 - 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 64 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 64 is 100%, so we can write it down as 64=100%.
4. We know, that x is 8.72% of the output value, so we can write it down as x=8.72%.
5. Now we have two simple equations:
1) 64=100%
2) x=8.72%
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:
64/x=100%/8.72%
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 8.72% of 64

64/x=100/8.72
(64/x)*x=(100/8.72)*x       - we multiply both sides of the equation by x
64=11.467889908257*x       - we divide both sides of the equation by (11.467889908257) to get x
64/11.467889908257=x
5.5808=x
x=5.5808

now we have:
8.72% of 64=5.5808
