To divide fractions, you multiply by the reciprocal of the divisor. This means you can rewrite the problem as follows:
\[ \frac{11}{3} \div \frac{2}{3} = \frac{11}{3} \times \frac{3}{2} \]
Now, multiply the fractions:
\[ \frac{11 \times 3}{3 \times 2} = \frac{33}{6} \]
Next, simplify \(\frac{33}{6}\):
\[ \frac{33 \div 3}{6 \div 3} = \frac{11}{2} \]
So, the answer is:
\(\mathbf{b. , 11/2}\)
