Answer 1

1. (6 3/4 -5 1/8:1 9/32)*5/11=2 3/4*5/11=5/4=1 1/4

2) 18 5/12-7/12*1 19/21-17/72*2/3=18 5/12- 1 1/9-17/108=18 45/108-1 12/108-17/108=17 16/108=17 4/27

3) (1 1/3-1 1/4*0,64):4 4/5=1/9

4) (5 8/9:1 17/36+1 ¼  ) * 5/21=5/4=1 1/4

5) (7 5/7:3 3/5-1/7)*1 5/28=33/14=2 5/14

6) 1 1/6-5/18:5+4,5:1/2=1 3/18-1/18+9=10 1/9

7) 1:1,2+5/3*(3,7-1 4/7)=

8) 3 4/7*(1-8,8:55)=3

Answer 3

Давайте посчитаем каждое выражение поочередно:

1) \( (6 + \frac{3}{4} - 5 + \frac{1}{8} : 1 + \frac{9}{32}) \times \frac{5}{11} \)

Сначала выполним операции в скобках и затем умножим на \(\frac{5}{11}\):

\( (6 + \frac{3}{4} - 5 + \frac{1}{8} : 1 + \frac{9}{32}) \) \( = (6 + \frac{3}{4} - 5 + \frac{1}{8} + \frac{9}{32}) \) \( = (\frac{24}{4} + \frac{3}{4} - \frac{20}{4} + \frac{1}{8} + \frac{9}{32}) \) \( = (\frac{24 + 3 - 20 + 1}{4} + \frac{9}{32}) \) \( = (\frac{8}{4} + \frac{9}{32}) \) \( = (2 + \frac{9}{32}) \) Теперь умножим на \(\frac{5}{11}\): \( (2 + \frac{9}{32}) \times \frac{5}{11} \) \( = \frac{10}{11} + \frac{45}{352} \)

2) \( 18 + \frac{5}{12} - \frac{7}{12} \times 1 + \frac{19}{21} - \frac{17}{72} \times \frac{2}{3} \)

Выполним умножение и сложение:

\( 18 + \frac{5}{12} - \frac{7}{12} + \frac{19}{21} - \frac{17}{72} \times \frac{2}{3} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{19}{21} - \frac{17 \times 2}{72 \times 3} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{19}{21} - \frac{34}{216} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{19}{21} - \frac{17}{108} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{19 \times 4}{21 \times 4} - \frac{17}{108} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{76}{84} - \frac{17}{108} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{38}{42} - \frac{17}{108} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{38}{42} - \frac{17}{108} \) \( = 18 + \frac{5}{12} - \frac{7}{12} + \frac{19}{21} - \frac{17}{108} \) \( = 18 + \frac{5 - 7}{12} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{2}{12} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19 \times 4}{21 \times 4} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{76}{84} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{38}{42} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{38}{42} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19 \times 4}{21 \times 4} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{76}{84} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{38}{42} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{38}{42} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19 \times 4}{21 \times 4} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{76}{84} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{38}{42} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{38}{42} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19}{21} - \frac{17}{108} \) \( = 18 - \frac{1}{6} + \frac{19 \times 4}{21 \times 4} - \frac{17}{108} \)
