Answer 2

$3 \frac{1}{8} - 2 \frac{2}{3} + \frac{1}{6}= 1\frac{3-16+4}{24 }=1- \frac{9}{24}= \frac{15}{24}=\frac{5}{8}\\\\ 4 \frac{3}{5} - 2 + \frac{1}{10}=2 \frac{6+1}{10} =2 \frac{7}{10} \\\\ 3 \frac{7}{8} - 2 \frac{3}{4} + \frac{1}{2} =1 \frac{7-6+4}{8}=1 \frac{5}{8} \\\\ 3 \frac{5}{14} - 1 - \frac{6}{7} =2 \frac{5-12}{14} =2- \frac{7}{14}=1 \frac{1}{2}$
