Answer 1

$\frac{5}{16} + \frac{7}{12} = \frac{5 \times 3 + 7 \times 4}{48} = \frac{15 + 28}{48} = \frac{43}{48} \\ \frac{3}{5} - \frac{4}{7} = \frac{3 \times 7 + 4 \times 5}{35} = \frac{21 + 20}{35} = \frac{41}{35} = 1 \frac{6}{35} \\ 1 - \frac{19}{36} = \frac{36}{36} - \frac{19}{36} = \frac{17}{36} \\ 6 - \frac{5}{13} = 5 \frac{13}{13} - \frac{5}{13} = 5 \frac{8}{13} \\ 7 \frac{2}{3} - 3 \frac{7}{16} = 7 \frac{2\times 16}{48} - 3 \frac{7 \times 3}{48} = 7 \frac{32}{48} - 3 \frac{21}{48} = 4 \frac{11}{48} \\ 1 \frac{3}{8} + 5 \frac{1}{6} = 1 \frac{3 \times 3}{24} + 5 \frac{1 \times 4}{24} = 1\frac{9}{24} + 5 \frac{4}{24} = 6 \frac{13}{24}$
