Question

Ms. Nellies has 2 pints 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 3-pint servings of vinegar she has.
Are Trey's number line model and equation correct?

Answer 1

Trey's Number line model is incorrect because it represents the expression 2 1/2 x 3/8. The correct equation is 2 1/2 ➗ 3/8 = 6 2/3. Ms. Nellies has enough vinegar for 6 groups of students

Answer 2

Incorrect,

2 1/2 divided by 3/8

2 1/2 divided by 3/8 = 6 2/3
