$- 15$

#### Explanation:

Let the number be $x$. The phrase Nine less than a number suggests that $9$ has been subtracted from the number. So, we can write it as $x - 9$. Then, it also states that the result will be $- 24$.

So, we get:

$x - 9 = - 24$

$x = - 24 + 9$

$= - 15$

Therefore, the number is $- 15$.
