Answer 1

Ответ:

Пошаговое объяснение:

1 . 1 4/9 = 13/9 ; 3 3/5 = 18/5 ; 7 5/6 = 47/6 .

2 . 13/7 = 1 6/7 ; 9/5 = 1 4/5 ; 13/8 = 1 5/8 .

3 . 3/13 + 1/13 = 4/13 ; 3/9 + 3/9 = 6/9 = 2/3 ; 4/13 + 3/13 = 7/13 .

A . 2/5 + 1/5 = 3/5 ; Б . 3/7 + 2/7 = 5/7 ;

8/17 + 5/17 = 13/17 ; 7/10 + 2/10 = 9/10 ;

7/9 + 2/9 = 9/9 = 1 ; 13/15 - 6/15 = 7/15 ;

9/10 + 2/10 = 11/10 = 1 1/10 ; 8/11 + 3/11 = 11/11 = 1 ;

7/17 + 9/17 = 16/17 . 23/100 - 10/100 = 13/100 .
