Answer 1

Resolvemos :

$\dfrac{1}{4}+ \dfrac{1}{6}= \dfrac{6+4}{24}= \dfrac{10:2}{24:2}= \dfrac{5}{12}$

$\dfrac{3}{8}+ \dfrac{1}{6} = \dfrac{18+8}{48} = \dfrac{26:2}{48:2}= \dfrac{13}{24}$

$\dfrac{1}{6}+ \dfrac{2}{9}= \dfrac{9+12}{54}= \dfrac{21:3}{54:3} = \dfrac{7}{18}$

$\dfrac{3}{4}+ \dfrac{1}{6}= \dfrac{18+4}{24}= \dfrac{22:2}{24:2}= \dfrac{11}{12}$

$\dfrac{1}{3} + \dfrac{1}{4}= \dfrac{4+3}{12}= \dfrac{7}{12}$

$\dfrac{1}{2}+ \dfrac{2}{5}= \dfrac{5+4}{10} = \dfrac{9}{10}$

$\dfrac{1}{3}+ \dfrac{3}{5} = \dfrac{5+9}{15}= \dfrac{14}{15}$

$\dfrac{3}{4}+ \dfrac{1}{5} =\dfrac{15+4}{20}= \dfrac{19}{20}$
