Olá Tudo Bom!!

a)

$= \frac{2}{9} + \frac{5}{9} = \frac{2 + 5}{9} = \frac{7}{9}$

b)

$= \frac{5}{6} - \frac{2}{6} = \frac{5 - 2}{6 } = \frac{3 {}^{ \div 3} }{6 {}^{ \div 3} } = \frac{1}{2}$

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

d)


$= \frac{7}{8} - \frac{4}{9} = \frac{63 - 32}{72} = \frac{31}{72}$

e)

$= \frac{1}{7} + \frac{3}{5} + \frac{9}{14} = \frac{10 + 42 + 45}{70} = \frac{97}{70}$

f)
$= 3 - \frac{14}{5} = \frac{15 - 14}{5} = \frac{1}{5}$

g)

$= 1 \frac{2}{11} + \frac{7}{10} = \frac{2}{11} + \frac{7}{10} = \frac{97}{110}$

h)

$= 2 \frac{1}{5} - 1 \frac{1}{6} = \frac{2}{5} - \frac{1}{6} = \frac{7}{30}$

i)

$= 7 + \frac{2}{9} = \frac{63 + 2}{9} = \frac{65}{9}$

j)

$= \frac{3}{4} - \frac{1}{6} = \frac{9 - 2}{12} = \frac{7}{12}$

k)

$= \frac{1}{5} + 2 + \frac{7}{8} = \frac{8 + 80 + 35}{40} = \frac{123}{40}$

l)

$= 3 \frac{2}{5} - \frac{1}{7} = \frac{6}{5} - \frac{1}{7} = \frac{37}{35}$
