Answer 1

$(4 \times \frac{3}{5} - 2 \times \frac{1}{5} \div 1 \times \frac{1}{10} = ( \frac{23}{5} - \frac{11}{5} ) \div \frac{11}{10} = \frac{12}{5} \times \frac{10}{11} = 12 \times \frac{2}{11} = \frac{24}{11} = 2 \times \frac{2}{11} \\ (1 \times \frac{7}{10} + \frac{4}{5} ) \div 1 \times \frac{7}{8} = (\frac{17}{10} + \frac{4}{5}) \div \frac{15}{8} = \frac{5}{2} \times \frac{8}{15} = \frac{4}{3} = 1 \times \frac{1}{3}$
