$1. : 5 frac{1}{4} + 4 frac{1}{3} = frac{21}{4} + frac{13}{3} = frac{63 + 52}{12} = frac{115}{12}$

$2. : 3 frac{1}{3} + frac{1}{2} = frac{10}{3} + frac{1}{2} = frac{20 + 3}{6} = frac{23}{6}$

$3. : 8frac{2}{3} - 5 frac{2}{5} = frac{26}{3} - frac{27}{5} = frac{130 - 81}{15} = frac{49}{15}$

$4. : 5 frac{7}{6} - 2 frac{1}{4} = frac{37}{6} - frac{9}{4} = frac{111 - 18}{2} = frac{93}{2}$
