Answer 1

Здравствуйте!
$(8 frac{7}{12} - 2 frac{17}{36} ) times 2 frac{7}{10} - 4 frac{1}{3} = (8 frac{21}{36} - 2 frac{17}{36} ) times 2 frac{7}{10} - 4 frac{1}{3} = 6 frac{4}{36} times frac{27}{10} - 4 frac{1}{3}= 6 frac{1}{9} times frac{27}{10} - 4 frac{1}{3} = frac{55 times 27}{9 times 10} - 4 frac{1}{3} = frac{11 times 3}{2} - 4 frac{1}{3} = frac{33}{2} - frac{13}{3} = frac{99}{6} - frac{26}{6} = frac{73}{6} = 12 frac{1}{6}$
ОТВЕТ: 12 1/6
