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

The answer is 90. 90 + 10 = 100 - 10 = 90
Answer:
GCF: 2xy
Step-by-step explanation:
2x^2y = 2 * x * x * y
4xy^3 = 2 * 2 * x * y * y * y
12x^2y^2 = 2 * 2 * 3 * x * x * y * y
Each monomial has been broken up into all its factors.
Below are the common factors shown in bold.
2x^2y = 2 * x * x * y
4xy^3 = 2 * 2 * x * y * y * y
12x^2y^2 = 2 * 2 * 3 * x * x * y * y
All terms have in common one factor 2, one factor x, and one factor y.
GCF: 2xy
