1. $3 frac{2}{3} + 4 frac{4}{5}$

= (3 + 4) + ( $frac{2}{3} + frac{4}{5}$ )

= 7 + ( $frac{2 times 5 }{3 times 5} + frac{4 times 3}{5 times 3}$ )

= 7 + ( $frac{10}{15} + frac{12}{15}$ )

= 7 + ( $frac{22}{15}$ )

= 7 + 1 $frac{7}{15}$

= 8 $frac{7}{15}$

2. $4 frac{1}{2} + 2 frac{1}{3}$

= (4 + 2) + ( $frac{1}{2} + frac{1}{3}$ )

= 6 + ( $frac{1 times 3}{2 times 3} + frac{1 times 2}{3 times 2}$ )

= 6 + ( $frac{3}{6} + frac{2}{6}$ )

= 6 + $frac{5}{6}$

= 6 $frac{5}{6}$

$:$

$5 frac{5}{6} + 2 frac{1}{4}$

= (5 + 2) + ( $frac{5}{6} + frac{1}{4}$ )

= 7 + ( $frac{5 times 2}{6 times 2} + frac{1 times 3}{4 times 3}$ )

= 7 + ( $frac{10}{12} + frac{3}{12}$ )

= 7 + $frac{13}{12}$

= 7 + 1 $frac{1}{12}$

= 8 $frac{1}{12}$
