What is 11.7 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 11.7% of the output value, so we can write it down as x=11.7%.
5. Now we have two simple equations:
1) 72=100%
2) x=11.7%
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%/11.7%
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 11.7% of 72

72/x=100/11.7
(72/x)*x=(100/11.7)*x       - we multiply both sides of the equation by x
72=8.5470085470085*x       - we divide both sides of the equation by (8.5470085470085) to get x
72/8.5470085470085=x
8.424=x
x=8.424

now we have:
11.7% of 72=8.424
