Answer: The correct answer is 3.
Step-by-step explanation:
Let the number of ninths needed be taken as 'x'
We need to find the number of ninths needed to make;
[tex]\frac{1}{3}[/tex],
The equation for this becomes:
[tex]\frac{1}{9}\times x=\frac{1}{3}\\\\x=\frac{9}{3}\\\\x=3[/tex]
Hence, we need 3 times ninths to get us the fraction of [tex]\frac{1}{3}[/tex].
