Which verbal expression best describes the algebraic expression 2x : 4?

The sum of two and some number divided by four

The product of some number and four divided by two

The quotient of two and some number times four

The quotient of two times some number and four

Let's reason through the answers ...

A) Do you see any sums? Any addition? Me neither ... it's not A.

B) Well I see a product of 2 and "some number," but are we dividing by 2? Nope. Not B.

C) I see a quotient (2x) divided by 4, but the "some number" is not being multiplied by four. Not C.

D) Well this is the only one left, so it better be this one! We have a quotient, and we have two times some number (2x). The quotient (the division) is of 2x and four. This is it! It's D.
