What is 43.72 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 43.72% of the output value, so we can write it down as x=43.72%.
5. Now we have two simple equations:
1) 72=100%
2) x=43.72%
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:
72/x=100%/43.72%
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 43.72% of 72

72/x=100/43.72
(72/x)*x=(100/43.72)*x       - we multiply both sides of the equation by x
72=2.2872827081427*x       - we divide both sides of the equation by (2.2872827081427) to get x
72/2.2872827081427=x
31.4784=x
x=31.4784

now we have:
43.72% of 72=31.4784
