79 is what percent of 9 - 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 9 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 9, so we can write it down as 100%=9.
4. We know, that x% equals 79 of the output value, so we can write it down as x%=79.
5. Now we have two simple equations:
1) 100%=9
2) x%=79
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%=9/79
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79 is what percent of 9

100%/x%=9/79
(100/x)*x=(9/79)*x       - we multiply both sides of the equation by x
100=0.11392405063291*x       - we divide both sides of the equation by (0.11392405063291) to get x
100/0.11392405063291=x
877.77777777778=x
x=877.77777777778

now we have:
79 is 877.77777777778% of 9
