Answer:

incorrect; 2½ ÷ ¾ = 3⅓; 2½ ÷ ⅜ = 6⅔; six

Step-by-step explanation:

Assume that Trey's number line model is like the first one below.

That model is incorrect.

The distance from 0 to 1 has four tick marks, so each mark represents the fraction ¼.

Trey is jumping three of them (¾) at a time.

Trey's number line represents the expression

2½ ÷ ¾ = 3⅓

The correct number line model is the second one below.

It represents the expression

2½ ÷ ⅜ = 6⅔

Ms. Nellies has enough vinegar for six groups of students
