Answer 1

let's firstly convert the mixed fractions to improper fractions, then subtract.

`\stackrel{mixed}{9(6)/(7)}\implies \cfrac{9\cdot 7+6}{7}\implies \stackrel{improper}{\cfrac{69}{7}}~\hfill \stackrel{mixed}{2(3)/(7)} \implies \cfrac{2\cdot 7+3}{7} \implies \stackrel{improper}{\cfrac{17}{7}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{69}{7}~~ - ~~\cfrac{17}{7}\implies \cfrac{69-17}{7}\implies \cfrac{52}{7}\implies 7(3)/(7)`
