Final answer:
The algebraic expression 12/w represents 12 divided by a number, the quotient of 12 and a number, and a number divided into 12. These refer to the division of 12 by an unknown number.
Step-by-step explanation:
The algebraic expression 12/w can be represented by several phrases, each describing a division operation involving the number 12 and a variable (w), which represents 'a number.' The correct phrases that can be represented by 12/w are:
- 12 divided by a number
- the quotient of 12 and a number
- a number divided into 12
These phrases accurately describe the operation of dividing 12 by some unknown value represented by the variable w. The expression does not represent a number divided by 12, nor does it represent the product of 12 and a number, which would require a multiplication sign instead.
