3/20×25=3 3/4

7/16×20=8 3/4

5/8×24=2 1/2

35/36÷14=5/72

18/19÷36=1/38

15/16÷10= 3/32

24/25÷6=0.16

12/17÷36=1/51

5. 1/6×4=2/3

2. 1/9×15=1/135

3. 1/8×16=2

4. 1/4×6= 1.5

1. 7/12×18=10 1/2

3. 1/5÷24=1/120

4. 1/5÷14= 1/70

6. 3/4÷18=1/24

1. 1/15÷32=1/480

2. 1/7÷30=1/210

Пошаговое объяснение:

2. 1/9×15=1·159 = 1*15/9 = 5 · 3/3 · 3 = 5/3 = 1·3 + 2/3 = 1 2/3

3. 1/8×16=1/8×16 = 1·16/8 = 16/8 = 2 · 88 = 2

4. 1/4×6=1/4×6 = 1·6/4 = 6/4 = 3 · 2/2 · 2 = 3/2 = 1·2 + 1/2 = 1 1/2 = 1.5

Answer 3

Давайте рассмотрим каждое уравнение по очереди:

1. (4/9) × 6 = (4/9) × (6/1) = (4 * 6) / (9 * 1) = 24/9 = 8/3

2. (18/25) × 15 = (18/25) × (15/1) = (18 * 15) / (25 * 1) = 270/25 = 54/5

3. (3/20) × 25 = (3/20) × (25/1) = (3 * 25) / (20 * 1) = 75/20 = 15/4

4. (7/16) × 20 = (7/16) × (20/1) = (7 * 20) / (16 * 1) = 140/16 = 35/4

5. (5/8) × 24 = (5/8) × (24/1) = (5 * 24) / (8 * 1) = 120/8 = 15

6. (35/36) ÷ 14 = (35/36) ÷ (14/1) = (35/36) × (1/14) = (35 * 1) / (36 * 14) = 35/504 = 5/72

7. (18/19) ÷ 36 = (18/19) ÷ (36/1) = (18/19) × (1/36) = (18 * 1) / (19 * 36) = 18/684 = 3/114 = 1/38

8. (15/16) ÷ 10 = (15/16) ÷ (10/1) = (15/16) × (1/10) = (15 * 1) / (16 * 10) = 15/160 = 3/32

9. (24/25) ÷ 6 = (24/25) ÷ (6/1) = (24/25) × (1/6) = (24 * 1) / (25 * 6) = 24/150 = 4/25

10. (12/17) ÷ 36 = (12/17) ÷ (36/1) = (12/17) × (1/36) = (12 * 1) / (17 * 36) = 12/612 = 2/102 = 1/51

11. (1/6) × 4 = (1/6) × (4/1) = (1 * 4) / (6 * 1) = 4/6 = 2/3

12. (1/9) × 15 = (1/9) × (15/1) = (1 * 15) / (9 * 1) = 15/9 = 5/3

13. (1/8) × 16 = (1/8) × (16/1) = (1 * 16) / (8 * 1) = 16/8 = 2

14. (1/4) × 6 = (1/4) × (6/1) = (1 * 6) / (4 * 1) = 6/4 = 3/2

15. (7/12) × 18 = (7/12) × (18/1) = (7 * 18) / (12 * 1) = 126/12 = 63/6 = 21/2

16. (1/5) ÷ 24 = (1/5) ÷ (24/1) = (1/5) × (1/24) = (1 * 1) / (5 * 24) = 1/120

17. (1/5) ÷ 14 = (1/5) ÷ (14/1) = (1/5) × (1/14) = (1 * 1) / (5 * 14) = 1/70

18. (3/4) ÷ 18 = (3/4) ÷ (18/1) = (3/4) × (1/18) = (3 * 1) / (4 * 18) = 3/72 = 1/24

19. (1/15) ÷ 32 = (1/15) ÷ (32/1) = (1/15) × (1/32) = (1 * 1) / (15 * 32) = 1/480

20. (1/7) ÷ 30 = (1/7) ÷ (30/1) = (1/7) × (1/30) = (1 * 1) / (7 * 30) = 1/210
