Question

1/2-1/3, 3/5-4/7, 5/7-1/6, 8/9-0, 3/4+4/5, 3/4+2/9Помогите плиз срочно

Answer 1

1/2-1/3=1/6
3/5-4/7=1/35
5/7-1/6=23/42
8/9-0=8/9
3/4+4/5=1,55
3/4+2/9=35/36

Answer 2

Давайте рассмотрим каждое выражение по отдельности:

1. 1/2 - 1/3: To subtract fractions, we need to have a common denominator. In this case, the common denominator is 6. So, we have: 1/2 = 3/6 1/3 = 2/6 Subtracting these fractions, we get: 3/6 - 2/6 = 1/6

2. 3/5 - 4/7: Again, we need a common denominator to subtract fractions. The common denominator here is 35. So, we have: 3/5 = 21/35 4/7 = 20/35 Subtracting these fractions, we get: 21/35 - 20/35 = 1/35

3. 5/7 - 1/6: To subtract fractions, we need a common denominator. The common denominator here is 42. So, we have: 5/7 = 30/42 1/6 = 7/42 Subtracting these fractions, we get: 30/42 - 7/42 = 23/42

4. 8/9 - 0: Any number subtracted by 0 is equal to the number itself. So, we have: 8/9 - 0 = 8/9

5. 3/4 + 4/5: To add fractions, we need a common denominator. The common denominator here is 20. So, we have: 3/4 = 15/20 4/5 = 16/20 Adding these fractions, we get: 15/20 + 16/20 = 31/20

6. 3/4 + 2/9: Again, we need a common denominator to add fractions. The common denominator here is 36. So, we have: 3/4 = 27/36 2/9 = 8/36 Adding these fractions, we get: 27/36 + 8/36 = 35/36

I hope this helps! Let me know if you have any further questions.
