What is 48.9 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 48.9% of the output value, so we can write it down as x=48.9%.
5. Now we have two simple equations:
1) 72=100%
2) x=48.9%
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%/48.9%
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 48.9% of 72

72/x=100/48.9
(72/x)*x=(100/48.9)*x       - we multiply both sides of the equation by x
72=2.0449897750511*x       - we divide both sides of the equation by (2.0449897750511) to get x
72/2.0449897750511=x
35.208=x
x=35.208

now we have:
48.9% of 72=35.208
