To solve the expression \( \frac{22}{3} \cdot \frac{18}{11} \div \frac{4}{7} \), follow these steps:

1. Perform the multiplication first: \[ \frac{22}{3} \cdot \frac{18}{11} = \frac{22 \cdot 18}{3 \cdot 11} = \frac{396}{33} = 12 \]

2. Now, divide by \( \frac{4}{7} \): \[ 12 \div \frac{4}{7} = 12 \cdot \frac{7}{4} = \frac{84}{4} = 21 \]

The result of the expression is 21.
