79 is what percent of 771 - 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 771 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 771, so we can write it down as 100%=771.
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%=771
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%=771/79
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 771

100%/x%=771/79
(100/x)*x=(771/79)*x       - we multiply both sides of the equation by x
100=9.7594936708861*x       - we divide both sides of the equation by (9.7594936708861) to get x
100/9.7594936708861=x
10.246433203632=x
x=10.246433203632

now we have:
79 is 10.246433203632% of 771
