What is 72.87 percent of 80 - 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 80 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 80 is 100%, so we can write it down as 80=100%.
4. We know, that x is 72.87% of the output value, so we can write it down as x=72.87%.
5. Now we have two simple equations:
1) 80=100%
2) x=72.87%
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:
80/x=100%/72.87%
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 72.87% of 80

80/x=100/72.87
(80/x)*x=(100/72.87)*x       - we multiply both sides of the equation by x
80=1.3723068478112*x       - we divide both sides of the equation by (1.3723068478112) to get x
80/1.3723068478112=x
58.296=x
x=58.296

now we have:
72.87% of 80=58.296
