Answer 1

2 1/14
The work is shown below

Answer 2

`\bf \stackrel{mixed}{3(2)/(7)}\implies \cfrac{3\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{23}{7}}~\hfill \stackrel{mixed}{4(3)/(7)}\implies \cfrac{4\cdot 7+3}{7}\implies \stackrel{improper}{\cfrac{31}{7}} \\\\\\ \stackrel{mixed}{5(9)/(14)}\implies \cfrac{5\cdot 14+9}{14}\implies \stackrel{improper}{\cfrac{79}{14}} \\\\[-0.35em] ~\dotfill`

`\bf \left( \cfrac{23}{7}+\cfrac{31}{7} \right)-\cfrac{79}{14}\implies \left( \cfrac{23+31}{7} \right)-\cfrac{79}{14}\implies \cfrac{54}{7}-\cfrac{79}{14}\implies \stackrel{\textit{using an LCD of 14}}{\cfrac{(2)54-(1)79}{14}} \\\\\\ \cfrac{108-79}{14}\implies \cfrac{29}{14}\implies 2(1)/(14)`
