80 is what percent of 725 - 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 725 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 100% equals 725, so we can write it down as 100%=725.
4. We know, that x% equals 80 of the output value, so we can write it down as x%=80.
5. Now we have two simple equations:
1) 100%=725
2) x%=80
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:
100%/x%=725/80
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 80 is what percent of 725

100%/x%=725/80
(100/x)*x=(725/80)*x       - we multiply both sides of the equation by x
100=9.0625*x       - we divide both sides of the equation by (9.0625) to get x
100/9.0625=x
11.034482758621=x
x=11.034482758621

now we have:
80 is 11.034482758621% of 725
