72 is what percent of 806 - 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 806 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 806, so we can write it down as 100%=806.
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%=806
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%=806/72
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 806

100%/x%=806/72
(100/x)*x=(806/72)*x       - we multiply both sides of the equation by x
100=11.1944444444*x       - we divide both sides of the equation by (11.1944444444) to get x
100/11.1944444444=x
8.93300248139=x
x=8.93300248139

now we have:
72 is 8.93300248139% of 806
