Answer:
the equation is incorrect
Step-by-step explanation:
Let u show the equation
The correct equation is [tex]2\frac{1}{2} \div \frac{3}{8}[/tex]
= 2 1/2 ➗ 3/8
= 5/2 ➗ 3/8
[tex]= \frac{ 5 \times 8}{2 \times 3}[/tex]
[tex]= \frac{40}{6} \\\\ = \frac{20}{3}[/tex]
[tex]= 6\frac{2}{3}[/tex]
Hence, the equation is incorrect
Trey's Number line model is incorrect because it represents the expression
[tex]2\frac{1}{2} \div \frac{3}{8}[/tex]
Ms. Nellies has enough vinegar for 6 groups of students as [tex]2\frac{1}{2} \div \frac{3}{8}[/tex]
