What is 17.61 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 17.61% of the output value, so we can write it down as x=17.61%.
5. Now we have two simple equations:
1) 72=100%
2) x=17.61%
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%/17.61%
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 17.61% of 72

72/x=100/17.61
(72/x)*x=(100/17.61)*x       - we multiply both sides of the equation by x
72=5.6785917092561*x       - we divide both sides of the equation by (5.6785917092561) to get x
72/5.6785917092561=x
12.6792=x
x=12.6792

now we have:
17.61% of 72=12.6792
