Пошаговое объяснение:

1) 4/13+7/13 = 11/13

2) 2/9+7/9 = 9/9 = 1

3) 8/17+11/17 = 19/17 = 1 2/17

4) 14/15-3/15 = 11/15

5) 14/18-4/18 = 10/18 = 5/9

6) 7/9-4/9 ​= 3/9 = 1/3

Answer 3

Sure, I can help you with these calculations. Here are the results for each of the expressions:

1. 4/13 + 7/13 = (4 + 7) / 13 = 11/13

2. 2/9 + 7/9 = (2 + 7) / 9 = 9/9 = 1 (since 9/9 is equivalent to 1)

3. 8/17 + 11/17 = (8 + 11) / 17 = 19/17

4. 14/15 - 3/15 = (14 - 3) / 15 = 11/15

5. 14/18 - 4/18 = (14 - 4) / 18 = 10/18 = 5/9 (you can simplify 10/18 to 5/9 by dividing both the numerator and denominator by their greatest common divisor, which is 2)

6. 7/9 - 4/9 = (7 - 4) / 9 = 3/9 = 1/3 (you can simplify 3/9 to 1/3 by dividing both the numerator and denominator by their greatest common divisor, which is 3)
