Answer 1

Explicação passo-a-passo:

.

$2 \dfrac{3}{5} = \dfrac{2 \times 5 + 3}{5} = \dfrac{13}{5}$

$4 \dfrac{2}{3} = \dfrac{4 \times 3 + 2}{3} = \dfrac{14}{3}$

$3 \dfrac{3}{8} = \dfrac{3 \times 8 + 3}{8} = \dfrac{27}{8}$

$3 \dfrac{2}{3} = \dfrac{ 3 \times 3 + 2}{3} = \dfrac{11}{3}$

$1 \dfrac{2}{7} = \dfrac{1 \times 7 + 2}{7} = \dfrac{9}{7}$

$5 \dfrac{1}{10} = \dfrac{5 \times 10 + 1}{10} = \dfrac{51}{1 0 }$

$1 \dfrac{9}{11} = \dfrac{1 \times 11 + 9}{11} = \dfrac{20}{11}$

$2 \dfrac{9}{13} = \dfrac{2 \times 13 + 9}{13} = \dfrac{35}{13}$

$3 \dfrac{4}{9} = \dfrac{3 \times 9 + 4}{9} = \dfrac{31}{9}$

$7 \dfrac{2}{5} = \dfrac{7 \times 5 + 2}{5} = \dfrac{37}{5}$

$6 \dfrac{5}{7} = \dfrac{6 \times 7 + 5}{7} = \dfrac{47}{7}$

$3 \dfrac{10}{11} = \dfrac{ 3\times11 + 10 }{11} = \dfrac{43}{11}$
