72 is what percent of 779 - 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 779 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 779, so we can write it down as 100%=779.
4. We know, that x% equals 72 of the output value, so we can write it down as x%=72.
5. Now we have two simple equations:
1) 100%=779
2) x%=72
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%=779/72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 72 is what percent of 779

100%/x%=779/72
(100/x)*x=(779/72)*x       - we multiply both sides of the equation by x
100=10.819444444444*x       - we divide both sides of the equation by (10.819444444444) to get x
100/10.819444444444=x
9.2426187419769=x
x=9.2426187419769

now we have:
72 is 9.2426187419769% of 779
