Question

Вычислите:1/6+2/7 2) 11/18-5/12 3) 4 7/12+1 3/16 4) 8 17/20-6 7/10

Answer 1

$frac{1}{6} + frac{2}{7} = frac{7+12}{42} = frac{19}{42}$
$frac{11}{18} - frac{5}{12} = frac{22-15}{36} = frac{7}{36}$
$4 frac{7}{12} + 1 frac{3}{16} = frac{112+9}{48} = frac{121}{48} = 2 frac{25}{48}$
$8 frac{17}{20} - 6frac{7}{10} = frac{34-21}{5} = 2frac{3}{5}$
