Question

2 5/6-1 1/5*1 1/9+1 5/7:1 1/7

Answer 1

$2\frac{5}{6} -1\frac{1}{5}*1\frac{1}{9}+1\frac{5}{7} : 1\frac{1}{7} =\frac{17}{6} -\frac{6}{5} *\frac{10}{9} +\frac{12}{7} *\frac{7}{8} =\frac{17}{6}-\frac{4}{3} +\frac{3}{2} =\frac{17}{6} -\frac{12}{6} +\frac{9}{6} =\frac{14}{6} =\frac{7}{3}= 2\frac{1}{3}$
