1 Chelsea is converting a fraction into a decimal by dividing the numerator by the denominator. At which point during her division can she be sure that a sequence in her decimal expansion is about to be

repeated?

Which one is it?

Idon't know what's the answer lol

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.
