Step-by-step explanation:
Answer:
\begin{gathered}9 \frac{5}{6} - 4 \frac{3}{8} + 2 \frac{7}{12} \\ = \frac{59}{6} - \frac{35}{8} + \frac{31}{12} \\ = \frac{59}{6} - ( \frac{105 + 62}{24} ) \\ = \frac{59}{6} - \frac{167}{24} \\ = \frac{236 - 167}{24} \\ = \frac{69}{24} \\ = \frac{23}{8} \\ = 2 \frac{7}{8} \end{gathered}
