Answer 1

$\frac{12 \frac{4}{5} \times 3 \frac{3}{4} - 4 \frac{4}{11} \times 4 \frac{1}{8} }{11 \frac{2}{3} \times 2 \frac{4}{7} } = 1 \\ 1) \: 12 \frac{4}{5} \times 3 \frac{3}{4} = \frac{64 \times 15}{5 \times 4} = 16 \times 3 = 48 \\ 2) \: 4 \frac{4}{11} \times 4 \frac{1}{8} = \frac{48 \times 33}{11 \times 8} = 6 \times 3 = 18 \\ 3) \: 11 \frac{2}{3} \times 2 \frac{4}{7} = \frac{35 \times 18}{3 \times 7} = 5 \times 6 = 30 \\ 4) \: 48 - 18 = 30 \\ 5) \: \frac{30}{30} = 1 \\ \\ 1 \div \frac{2}{3} = \frac{3}{2} = 1 \frac{1}{2} = 1.5$
