What is 86.8 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 86.8% of the output value, so we can write it down as x=86.8%.
5. Now we have two simple equations:
1) 72=100%
2) x=86.8%
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%/86.8%
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 86.8% of 72

72/x=100/86.8
(72/x)*x=(100/86.8)*x       - we multiply both sides of the equation by x
72=1.1520737327189*x       - we divide both sides of the equation by (1.1520737327189) to get x
72/1.1520737327189=x
62.496=x
x=62.496

now we have:
86.8% of 72=62.496
