Answer 1

$\frac{3 \frac{1}{18} }{ \frac{1}{9} } \div \frac{3 \frac{2}{3} }{1 \frac{7}{20} } = (3 \frac{1}{18} \div \frac{1}{9} ) \div (3 \frac{2}{3} \div 1 \frac{7}{20} ) = \frac{55 \times 9}{18} \div \frac{11 \times 20}{3 \times 27} = \frac{55 \times 9}{18} \times \frac{3 \times 27}{11 \times 20} = \frac{3 \times 27}{2 \times 4} = \frac{81}{8} = 10 \frac{1}{8}$
