Question

$(- 1\frac{5}{9} *2 \frac{1}{7} + 1 \frac{7}{12}) * 1 \frac{1}{7}$

Answer 1

$1)-1 \frac{5}{9} *2 \frac{1}{7} =- \frac{14}{9} * \frac{15}{7} =- \frac{10}{3} \\ 2)- \frac{10}{3} +1 \frac{7}{12} =-( \frac{10}{3} - \frac{19}{12} )=-( \frac{40-19}{12} )=- \frac{21}{12} =- \frac{7}{4} \\ 3)- \frac{7}{4} *1 \frac{1}{7} =- \frac{7}{4} * \frac{8}{7} =-2$
