When are the fractional amounts 3/6 and 2/4 not equal?

Never. If you set up an equation making them equal to each other and you solve it, it will give you that they are equal. Even when you divide them separately (3 by 6 and 2 by 4 ) you get 1/2 for both. You can't change that. Look in the picture

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
