помогите пж срочно надо

Answer 1

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