Answer 1

$1)1 \frac{1}{15} :1 \frac{3}{5} = \frac{16}{15} : \frac{8}{5} = \frac{16}{15} * \frac{5}{8} = \frac{2}{3} \\ 2)3 \frac{1}{15} - \frac{2}{3} = \frac{46}{15} - \frac{10}{15} = \frac{36}{15}=2 \frac{2}{5} \\ 3)2 \frac{2}{5} + \frac{2}{5} =2 \frac{4}{5} \\ 4)2 \frac{4}{5} *2 \frac{1}{7} = \frac{14}{5}* \frac{15}{7} =6 \\ 5)6-1 \frac{1}{7} =4 \frac{6}{7}$
