Answer 1

$\frac{9 \frac{1}{2} \div 1.9 - 4 \frac{1}{5} }{2.32 \times \frac{15}{29} + \frac{4}{5} } + \frac{(6 + 7 \frac{1}{2}) \div15 }{(1 \frac{7}{15} + \frac{1}{3}) \times 5 } =0.5 \\ 1) \: 9 \frac{1}{2} \div 1.9 = \frac{19 \times 10}{2 \times 19} = 5 \\ 2) \: 5 - 4 \frac{1}{5} = 4 \frac{5}{5} - 4 \frac{1}{5} = \frac{4}{5} \\ 3) \: 2.32 \times \frac{15}{29} = \frac{58 \times 15}{25 \times 29} = \frac{2 \times 3}{5} = \frac{6}{5} \\ 4) \: \frac{6}{5} + \frac{4}{5} = \frac{10}{5} = 2 \\ 5) \: \frac{4}{5} \div 2 = \frac{4}{5 \times 2} = \frac{2}{5} \\ 6) \: 6 + 7 \frac{1}{2} = 13 \frac{1}{2} \\ 7) \: 13 \frac{1}{2} \div 15 = \frac{27}{2 \times 15} = \frac{9}{2 \times 5} = \frac{9}{10} \\8 ) \: 1 \frac{7}{15} + \frac{1}{3} = 1 \frac{7}{15} + \frac{5}{15} = 1 \frac{12}{15} = 1 \frac{4}{5} \\ 9) \: 1 \frac{4}{5} \times 5 = \frac{9 \times 5}{5} = 9 \\ 10) \: \frac{9}{10} \div 9 = \frac{9}{10 \times 9} = \frac{1}{10} \\ 11) \: \frac{2}{5} + \frac{1}{10} = \frac{4}{10} + \frac{1}{10} = \frac{5}{10} = 0.5$
