Answer 1

Ответ:

1) 2 2/11×7/8:7/11 = 3

2) 3 2/3×4 7/8:13/16 = 22

3) 1 1/3×2 2/3:4/9 = 8

4) 6 4/15×1/2:3 2/15 = 1

5) 8 1/3×1 5/7:2 8/21 = 6

6) 1 5/6×3 3/5:2 1/5 = 3

1339.

1) (6 1/4-4 1/8)×4+3 1/3:2 1/2 = 9/4×4+10/3×2/5 = 9+4/3 = 10 1/3

2) (2 4/9+1 1/6)×1 4/5-3 1/9:2 1/3 = 65/18×9/5-28/9×3/7 = 6 1/2-4/3 = 5 1/6

3) (2-1 7/12):(3/8-1/6)×3 1/4 = 5/12×5/24×13/4 = 13/2 = 6,5

4) (7/10-2/5)×(1/4+5/6):6 1/2 = 3/10×13)12÷13/2 = 3/10×1/6 = 1/20 = 0,05

Answer 2

Пошаговое объяснение:

№1

1) 6. 1/4 - 4. 1/8 = 6. 6/24 - 4. 3/24 = 2. 3/24 = 6. 1/8

2) 6. 1/8 * 4 = 49/8 * 4 = 49/2 * 1 = 49/2 = 24. 1/2

3) 3. 1/3 : 2. 1/2 = 10/3 : 5/2 = 10/3 * 2/5 = 20/15 = 4/3 = 1. 1/3

4) 24. 1/2 + 1. 1/3 = 24. 3/6 + 1. 2/6 = 25. 5/6

№2

1) 2. 4/9 + 1. 1/6 = 2. 8/18 + 1. 3/18 = 3. 11/18

2) 3. 11/18 * 1. 4/5 = 65/18 * 9/5 = 13/2 * 1/1 = 13/2 = 6. 1/2

3) 3. 1/9 : 2. 1/3 = 28/9 : 7/3 = 28/9 * 3/7 = 4/3 * 1/1 = 4/3 = 1. 1/3

4) 6. 1/2 - 1. 1/3 = 6. 3/6 - 1. 2/6 = 5. 1/6

№3

1) 2 - 1. 7/12 = 1. 12/12 - 1. 7/12 = 5/12

2) 3/8 - 1/6 = 9/24 - 4/24 =5/24

3) 5/12 : 5/24 = 5/12 * 24/5 = 1/1 * 2/1 = 2/1 = 2

4) 2 * 3. 1/4 = 2 * 13/4 = 26/4 = 6. 2/4 = 6. 1/2

№4

1) 7/10 - 2/5 = 7/10 - 4/10 = 3/10

2) 1/4 + 5/6 = 3/12 + 10/12 = 13/12

3) 3/10 * 13/12 = 1/10 * 13/4 = 13/40

4) 13/40 : 6. 1/2 = 13/40 : 13/2 = 13/40 * 2/13 = 1/20 * 1/1 = 1/20
