Question

(3 1/3+5 1/6)×2/5-2 2/4÷(1 1/2-2/5)+5 3/10 вычислите ​

Answer 1

Ответ:

$(3\frac{1}{3} +5\frac{1}{6} )*\frac{2}{5} -2\frac{2}{4} :(1\frac{1}{2} -\frac{2}{5} )+5\frac{3}{10} =\\(\frac{10}{3} +\frac{31}{6} )*\frac{2}{5} -\frac{10}{4} :(\frac{3}{2} -\frac{2}{5} )+\frac{53}{10} =\\(\frac{20}{6} +\frac{31}{6} )*\frac{2}{5} -\frac{10}{4} :(\frac{15}{10} -\frac{4}{10})+\frac{53}{10} =$

$\frac{51}{6} *\frac{2}{5} -\frac{10}{4} :\frac{11}{10} +\frac{53}{10} =\\\frac{17}{5} -\frac{10}{4} *\frac{10}{11} +\frac{53}{10} =\\\frac{17}{5} -\frac{25}{11} +\frac{53}{10} =\\\frac{374-250+583}{110} =\\\frac{707}{110} =\\6\frac{47}{110}$

Answer 2

Ответ:

6 47/110

Пошаговое объяснение:

1) 3 1/3 + 5 1/6 = 3 2/6 + 5 1/6 = 8 3/6 = 8 1/2

2) 8 1/2 * 2/5 = 17/2 * 2/5 = 17/5 = 3 2/5

3) 1 1/2 - 2/5 = 1 5/10 - 4/10 = 1 1/10

4) 2 2/4 : 1 1/10 = 10/4 : 11/10 = 10/4 * 10/11 = 10/2 * 5/11 = 50/22 = 25/11 = 2 3/11

5) 3 2/5 - 2 3/11 = 3 22/55 - 2 15/55 = 1 7/55

6) 1 7/55 + 5 3/10 = 1 70/550 + 5 165/550 = 6 235/550 = 6 47/110
