б)435+128
в)516+1112
г)1163 - 542

Answer 1

$frac{7}{24} - frac{5}{18} = frac{21-20}{72} = frac{1}{72}$
$frac{4}{35} + frac{1}{28} = frac{16+5}{140} = frac{21}{140} = frac{3}{20} = 0.15$
$frac{5}{16} + frac{11}{12} = frac{15+44}{48} = frac{49}{48} = 1frac{1}{48}$
$frac{11}{63} - frac{5}{42} = frac{22-15}{126} = frac{7}{126} = frac{1}{18}$
