(5-3/11):13+1/2

Answer 1

Ответ: 1

Пошаговое объяснение:

1) 3 + 7/11 = 3 7/11 = 40/11

2) 40/11 * 1/4 = 10/11

3) 10/11 - 1/22 = 20/22 - 1/22 = 19/22

4) 5 - 3/11 = 4 8/11 = 52/11

5) 52/11 : 13 = 52/11 * 1/13 = 4/11

6) 4/11 + 1/2 = 8/22 + 11/22 = 19/22

7) 19/22 : 19/22 = 1

====================

$1) 3+\frac{7}{11} = 3\frac{7}{11} = \frac{40}{11} \\ 2) \frac{40}{11} *\frac{1}{4} =\frac{10}{11} \\ 3)\frac{10}{11} -\frac{1}{22} =\frac{20}{22} -\frac{1}{22} =\frac{19}{22} \\ 4)5-\frac{3}{11} =4\frac{8}{11} =\frac{52}{11} \\ 5)\frac{52}{11} :13=\frac{52}{11} *\frac{1}{13} =\frac{4}{11} \\ 6)\frac{4}{11} +\frac{1}{2} =\frac{8}{22} +\frac{11}{22} =\frac{19}{22} \\ 7)\frac{19}{22} :\frac{19}{22} =1\\ \\ Otvet: 1$
