Answer 1

$1) \frac{4}{7} +\frac{1}{5} = \frac{4*5}{7*5} +\frac{1*7}{5*7} =\frac{20}{35} + \frac{7}{35} = \frac{27}{35}$

2)  $5\frac{3}{4}+$$3\frac{1}{5}$ = 8 + $\frac{3}{4}$$+\frac{1}{5}$ = $8+\frac{15}{20}+\frac{4}{20}$ = $8+\frac{19}{20}$ = $8\frac{19}{20}$

3) $\frac{9}{11}$ - $\frac{2}{3}$ = $\frac{27}{33}$ $- \frac{22}{33}$ = $\frac{5}{33}$

4) $2\frac{6}{35} + 3\frac{3}{10}$ = $5+\frac{6}{35} +\frac{3}{10} = 5+\frac{12}{70}+\frac{21}{70}=5\frac{33}{70}$
