Answer: The required number of ninths needed is 3.

Step-by-step explanation: We are given to find the number of ninths that will after combining together make the amount as $\dfrac{1}{3}.$

Let, 'n' be the required number of ninths.

Then, according to the given information, we have

$n\times\dfrac{1}{9}=\dfrac{1}{3}\\\\\\\Rightarrow n=9\times \dfrac{1}{3}\\\\\\\Rightarrow n=3.$

Therefore, required number of ninth needed is 3.

Thus, the answer is 3.
