Answer:
[tex] = > 8 \frac{1}{4} - 3 \frac{5}{6} [/tex]
[tex] = > \frac{33}{4} - \frac{23}{6} [/tex]
[tex] = > \frac{33 \times 3}{4 \times 3} - \frac{23 \times 2}{6 \times 2} [/tex]
[tex] = > \frac{99}{12} - \frac{46}{12} [/tex]
[tex] = > \frac{99 - 46}{12} [/tex]
[tex] = > \frac{53}{12} [/tex]
[tex] = > 4 \frac{5}{12} [/tex]
