77 is what percent of 756 - 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 756 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 756, so we can write it down as 100%=756.
4. We know, that x% equals 77 of the output value, so we can write it down as x%=77.
5. Now we have two simple equations:
1) 100%=756
2) x%=77
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%=756/77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77 is what percent of 756

100%/x%=756/77
(100/x)*x=(756/77)*x       - we multiply both sides of the equation by x
100=9.8181818181818*x       - we divide both sides of the equation by (9.8181818181818) to get x
100/9.8181818181818=x
10.185185185185=x
x=10.185185185185

now we have:
77 is 10.185185185185% of 756
