Answer 1

Ответ:

Пошаговое объяснение:

$(7\frac{30}{29} -1\frac{6}{29} )+(2+1+\frac{11}{23} +\frac{11}{15} )=6\frac{24}{29} +3+\frac{165+253}{345} =9+\frac{24}{29} +\frac{418}{345} =9+\frac{8280+12122}{10005} =\\\\\\9+\frac{20402}{10005} =9+2+\frac{392}{10005} =11\frac{392}{10005}$

Answer 2

1) 8 1/29 - 1 6/29 = 7 30/29 - 1 6/29 = 6 24/29

2) 2 11/23 + 1 11/15 = 2 165/345 + 1 253/345 = 3 418/345 = 4 73/345

3) 6 24/29 + 4 73/345 = 6 8280/10005 + 4 2117/10005 = 10 10397/10005 = 11 392/10005
