Question

Ms. Nellies

s of vinegar for her students to use in a science experiment. Each
group of students needs pint of vinegar. Trey draws the number line model and writes the
equation below to help Ms. Nellies figure out how many -pint servings of vinegar she has.
Are Trey's number line model and equation correct?

Answer 1

the equation is incorrect

Explanation:

Let u show the equation

The correct equation is
`2(1)/(2) / (3)/(8)`

= 2 1/2 ➗ 3/8

= 5/2 ➗ 3/8

`= ( 5 * 8)/(2 * 3)`

`= (40)/(6) \\\\ = (20)/(3)`

`= 6(2)/(3)`

Hence, the equation is incorrect

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

`2(1)/(2) / (3)/(8)`

Ms. Nellies has enough vinegar for 6 groups of students as
`2(1)/(2) / (3)/(8)`

`= 6(2)/(3)`
