8$\frac{3}{4}$ - 4$\frac{5}{6}$ = 3$\frac{11}{12}$
8$\frac{3}{4}$ - 4$\frac{5}{6}$ = 8$\frac{9}{12}$ - 4$\frac{10}{12}$ ........... (1) = 3$\frac{11}{12}$ ...................... (2) In Step (1), we rewrite the fractions with the common denominator of 4 and 6, which is 12. In Step (2), we subtract $\frac{10}{12}$ from $\frac{9}{12}$. Since this yields a negative answer (-$\frac{1}{12}$), we subtract the whole number by 1 and subtract the remaining value from that whole number (8 - 4 = 4 - $\frac{1}{12}$ = 3$\frac{11}{12}$).
