What is 97 percent of 80.64 - 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 80.64 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 80.64 is 100%, so we can write it down as 80.64=100%.
4. We know, that x is 97% of the output value, so we can write it down as x=97%.
5. Now we have two simple equations:
1) 80.64=100%
2) x=97%
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:
80.64/x=100%/97%
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% of 80.64

80.64/x=100/97
(80.64/x)*x=(100/97)*x       - we multiply both sides of the equation by x
80.64=1.0309278350515*x       - we divide both sides of the equation by (1.0309278350515) to get x
80.64/1.0309278350515=x
78.2208=x
x=78.2208

now we have:
97% of 80.64=78.2208
