77 is what percent of 3286 - 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 3286 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 3286, so we can write it down as 100%=3286.
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%=3286
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%=3286/77
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 3286

100%/x%=3286/77
(100/x)*x=(3286/77)*x       - we multiply both sides of the equation by x
100=42.675324675325*x       - we divide both sides of the equation by (42.675324675325) to get x
100/42.675324675325=x
2.3432744978698=x
x=2.3432744978698

now we have:
77 is 2.3432744978698% of 3286
