What is 97.2 percent of 115 - 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 115 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 115 is 100%, so we can write it down as 115=100%.
4. We know, that x is 97.2% of the output value, so we can write it down as x=97.2%.
5. Now we have two simple equations:
1) 115=100%
2) x=97.2%
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:
115/x=100%/97.2%
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 97.2% of 115

115/x=100/97.2
(115/x)*x=(100/97.2)*x       - we multiply both sides of the equation by x
115=1.0288065843621*x       - we divide both sides of the equation by (1.0288065843621) to get x
115/1.0288065843621=x
111.78=x
x=111.78

now we have:
97.2% of 115=111.78
