Answer 2

Explanation:

Let the number is n. We need to write an expression for "seven less than the quotient of nineteen and a number"

The quotient of nineteen and a number is
`(19)/(n)` and 7 less than this is
`(19)/(n)-7`

Now if n = 2, put the value of n in above expression,

`(19)/(n)-7=(19)/(2)-7\\\\=(5)/(2)\\\\=2.5`

So, the value of the above expression is 2.5 at n = 2.
