What is 17.28 percent of 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 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 72 is 100%, so we can write it down as 72=100%.
4. We know, that x is 17.28% of the output value, so we can write it down as x=17.28%.
5. Now we have two simple equations:
1) 72=100%
2) x=17.28%
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:
72/x=100%/17.28%
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 17.28% of 72

72/x=100/17.28
(72/x)*x=(100/17.28)*x       - we multiply both sides of the equation by x
72=5.787037037037*x       - we divide both sides of the equation by (5.787037037037) to get x
72/5.787037037037=x
12.4416=x
x=12.4416

now we have:
17.28% of 72=12.4416
