Answer 1

2. 1) 9 3/4 + 3 1/6 = 9 9/12 + 3 2/12 = 12 11/12

2) 7 8/9 - 2 2/3 = 7 8/9 - 2 6/9 = 5 2/9

3) 11 7/12 + 6 11/18 = 11 21/36 + 6 22/36 = 17 43/36 = 18 7/36

4) 5 5/9 - 2 4/7 = 5 35/63 - 2 36/63 = 2 62/63

5) 9 - 2 3/7 = 6 4/7

6) 7 5/16 + 4 1/6 + 3 3/8 = 7 15/48 + 4 8/48 + 3 18/48 = 14 41/48

7) 8 5/9 + 7 3/4 + 12 7/12 = 8 20/36 + 7 27/36 + 12 21/36 = 27 68/36 = 28 32/36 = 28 8/9

8) 6 7/8 - 3 1/3 + 5 5/16 = 6 42/48 - 3 16/48 + 5 15/48 = 8 41/48

9) 5 8/15 + 4 7/12 - 3 19/20 = 5 32/60 + 4 35/60 - 3 57/60 = 6 10/60 = 6 1/6

10) 5 9/14 - 2 3/7 + 6,7 = 5 9/14 - 2 6/14 + 6 7/10 = 5 45/70 - 2 30/70 + 6 35/40 = 9 50/40 = 10 10/40 = 10 1/4

3. 1) 5/6 * 3/20 = 1/8

2) 3/7 * 6/11 = 18/77

3) 10/11 * 11/26 = 10/26 = 5/13

4) 19/42 * 21/38 = 1/4

5) 3/4 : 33/20 = 3/4 * 20/33 = 5/11

6) 25/72 : 45/63 = 25/72 * 63/45 = 35/72

7) 8/15 : 24 = 8/15 : 24/1 = 8/15 * 1/24 = 1/45

8) 8 : 4/5 = 8/1 : 4/5 = 8/1 * 5/4 = 10

9) 2/3 * 6/7 : 4/7 = 4/7 : 4/7 = 1

10) 11/12 : 7/24 * 21/22 = 11/12 * 24/7 * 21/22 = 22/7 * 21/22 = 3

Answer 2

Пошаговое объяснение:

№3

1) 5/6 * 3/20 = 1/2 * 1/4 = (1*1)/(2*4) = 1/8

2) 3/7 * 6/11 = (3*6)/(7*11) = 18/77

3) 10/11 * 11/26 = 5/1 * 1/13 = (5*1)/(1*13) = 5/13

4) 19/42 * 21/38 = 1/2 * 1/2 = (1*1)/(2*2) = 1/4

5) 3/4 : 33/20 = 3/4 * 20/33 = 1/1 * 5/11 = 5/11

6) 25/72 : 45/63 = 25/72 * 63/45 = 5/8 * 7/9 = (5*7)/(8*9) = 35/72

7) 8/15 : 24 = 8/15 * 1/24 = 1/15 * 1/3 = (1*1)/(15*3) = 1/45

8) 8 : 4/5 = 8 * 5/4 = (8*5)/4 = 40/4 = 10

9) 2/3 * 6/7 : 4/7 = 2/3 * 6/7 * 7/4 = 2/3 * 3/1 * 1/2 = 2/3 * 3/2 = 1/1 * 1/1 = 1/1 = 1

10) 11/12 : 7/24 * 21/22 = 11/12 * 24/7 * 21/22 = 11/1 * 2/7 * 21/22 = 22/7 * 21/22 = 1/1 * 3/1 = 3/1 = 3
