Answer 1

$\frac{(1 \frac{1}{2} + 2 \frac{2}{3} + 3 \frac{3}{4} ) \times 3 \frac{3}{5} }{14 - 15 \frac{1}{8} \div 2 \frac{1}{5} } = 4\\ \\ - - - - - - - - - - - \\ 1) \: \: \: \: 1 \frac{1}{2} + 2 \frac{2}{3} + 3 \frac{3}{4} = 6 \frac{6 + 8 + 9}{12} = 6 \frac{23}{12} = 7 \frac{11}{12} \\ \\ 2) \: \: \: 7 \frac{11}{12} \times 3 \frac{3}{5} = \frac{95}{12} \times \frac{18}{5} = \frac{19 \times 3}{2} = \frac{57}{2} = 28 \frac{1}{2} \\ \\ 3) \: \: \: 15 \frac{1}{8} \div 2 \frac{1}{5} = \frac{121}{8} \times \frac{5}{11} = \frac{11 \times 5}{8} = \frac{55}{8} = 6 \frac{7}{8} \\ \\ 4) \: \: \: 14 - 6 \frac{7}{8} = 7 \frac{1}{8} \\ \\ 5) \: \: \: 28 \frac{1}{2} \div 7 \frac{1}{8} = \frac{57}{2} \div \frac{57}{8} = \frac{57 \times 8}{2 \times 57} = 4$
