The quotient of one and two times a number

The expression will be:

1/2 x n

Explanation:

The quotient of one and two means 1 divided by 2 (1/2). Then we need to multiply 1/2 by a number. The variable "n" represents "a number."

Answer: A quotient means a ratio or one quantity being divided by another, or in algebraic terms (a/b). In this case, the first quantity is "four times a number" represented in terms of x as (4x). The other quantity is just the number 9.
