6.85 is what percent of 77 - 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 77 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 77, so we can write it down as 100%=77.
4. We know, that x% equals 6.85 of the output value, so we can write it down as x%=6.85.
5. Now we have two simple equations:
1) 100%=77
2) x%=6.85
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%=77/6.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.85 is what percent of 77

100%/x%=77/6.85
(100/x)*x=(77/6.85)*x       - we multiply both sides of the equation by x
100=11.240875912409*x       - we divide both sides of the equation by (11.240875912409) to get x
100/11.240875912409=x
8.8961038961039=x
x=8.8961038961039

now we have:
6.85 is 8.8961038961039% of 77
