Answer 1

$(2 \frac{1}{3} + 3.5) \div ( - 4 \frac{1}{6} + 3.25) + 2 \frac{4}{11} = - 4 \\ 1) \: 2 \frac{1}{3} + 3.5 = 2 \frac{1}{3} + 3 \frac{1}{2} = 2 \frac{2}{6} + 3 \frac{3}{6} = 5 \frac{5}{6} \\ 2) \: - 4 \frac{1}{6} + 3.25 = - 4 \frac{1}{6} + 3 \frac{1}{4} = - 4 \frac{4}{24} + \\ = 3 \frac{6}{24} = - 3 \frac{28}{24} + 3 \frac{6}{24} = - \frac{22}{24} = - \frac{11}{12} \\3) \: 5 \frac{5}{6} \div ( - \frac{11}{12} ) = - \frac{35 \times 12}{6 \times 11} = - \frac{70}{11} = - 6 \frac{4}{11} \\ 4) \: 2 \frac{4}{11} - 6 \frac{4}{11} = - 4$

Answer 2

Ответ:

-4

Пошаговое объяснение:

1) 2 1/3 + 3,5 = 7/3 + 35/10 = 70/30 + 105/30 = 175/30 = 35/6

2) -4 1/6 + 3,25 = -25/6 + 325/100 = -25/6 + 13/4 = -50/12 + 39/12 = -11/12

3) 35/6 : (-11/12) = 35/6 * (-12/11) = 35/1 * (-2/11) = -70/11 = -6 4/11

4) -6 4/11 + 2 4/11 = -4
