What is 78.05 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 78.05% of the output value, so we can write it down as x=78.05%.
5. Now we have two simple equations:
1) 115=100%
2) x=78.05%
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%/78.05%
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 78.05% of 115

115/x=100/78.05
(115/x)*x=(100/78.05)*x       - we multiply both sides of the equation by x
115=1.2812299807816*x       - we divide both sides of the equation by (1.2812299807816) to get x
115/1.2812299807816=x
89.7575=x
x=89.7575

now we have:
78.05% of 115=89.7575
