\(\frac{11}{18} - \frac{4}{9} = \frac{11}{18} - \frac{4 \cdot 2}{9 \cdot 2} = \frac{11}{18} - \frac{8}{18} = \frac{11 - 8}{18} = \frac{3}{18} = \frac{1}{6}\)
\(\frac{1}{6} \cdot \frac{3}{16} = \frac{1 \cdot 3}{6 \cdot 16} = \frac{3}{96}\)
\(\frac{3}{96} = \frac{3 \div 3}{96 \div 3} = \frac{1}{32}\)
