To find the quotient of 8 divided by one-third (1/3), you can multiply 8 by the reciprocal of one-third.
The reciprocal of one-third (1/3) is three (3).
So, to find the quotient:
\[ 8 \div \frac{1}{3} = 8 \times 3 = 24 \]
Thus, the correct way to express this is to multiply 8 by 3. Therefore, the answer is:
3.
