Answer 1

Ответ:

Пошаговое объяснение:

1) 43 4/13+2 5/20 => НОК(13;20) = 260 =>43 80/260+2 65/260 =

= 45 (80+65)/260 = 45 145/260 = 45 29/52;

2)  98 6/23-13 11/69 => НОК(23;69) = 69 => 98 18/69 - 13 11/69 = 85 7/69;

3)  12 4/11-5 7/44 =>  НОК(11;44) = 44 => 12 16/44 - 5 7/44 = 7 9/44;

4) 19 4/31+11 7/62 =>  НОК(31;62) = 62 => 19 8/62 + 11 7/62 = 30 15/62.

5) 126  4/35-26  1/14 =>  НОК(35;14) = 70 => 126 8/70 - 26 5/70 =

100 (8-5)/70 =100 3/70.
