Answer:
D and E
Step-by-step explanation:
He divides the number line into 6 equal parts. Meaning that 6/6 would be the whole, and the denominator would be 6, or a simplified version of that.
so you got the generic 1/6, 2/6, 3/6, 4/6 and 5/6, which is D
but E is the simplified version of the previous one
2/6 simplifies into 1/3
4/6 simplifies ino 2/3
So technically E is correct as well, just a simplified version of D, thus your answer choices being D and E.
