1) $2 \frac{3}{5} +4 \frac{1}{5} =(2+4)+( \frac{3}{5} + \frac{1}{5} )=6+ \frac{3}{10}= \frac{63}{10} =6,3$ $\\ \\ 2) 3 \frac{1}{2} +5 \frac{3}{4} =(3+5)+( \frac{1}{2} + \frac{3}{4} )=8+ \frac{5}{4} = \frac{37}{4} =9,25 \\1) 7 \frac{5}{8} -4 \frac{1}{3} =(7-4)+( \frac{5}{8} - \frac{1}{3} )=3+ \frac{7}{24} = \frac{79}{24} \\ 2)9-2 \frac{5}{6} =8 \frac{6}{6} -2 \frac{5}{6} =(8-2)+( \frac{6}{6} - \frac{5}{6} )=6+ \frac{1}{6} = \frac{37}{6}$
