Question

Ms. Nellies

Answer 1

Answer:

the equation is incorrect

Step-by-step explanation:

Let u show the equation

The correct equation is $2\frac{1}{2} \div \frac{3}{8}$

= 2 1/2 ➗ 3/8

= 5/2 ➗ 3/8

$= \frac{ 5 \times 8}{2 \times 3}$

$= \frac{40}{6} \\\\ = \frac{20}{3}$

$= 6\frac{2}{3}$

Hence, the equation is incorrect

Trey's Number line model is incorrect because it represents the expression

$2\frac{1}{2} \div \frac{3}{8}$

Ms. Nellies has enough vinegar for 6 groups of students as $2\frac{1}{2} \div \frac{3}{8}$

$= 6\frac{2}{3}$
