Ответ:

1) 135/18; 84/18; 93/18; 62/18

2) 114/12; 64/12; 75/12; 106/12

3) 570/45; 342/45; 290/45; 186/45

Пошаговое объяснение:

1) 7 1/2 = (7*2+1)/2 = 15/2 = (15*9)/(2*9) = 135/18

4 2/3 = (4*3+2)/3 = 14/3 = (14*6)/(3*6) = 84/18

5 1/6 = (5*6+1)/6 = 31/6 = (31*3)/(6*3) = 93/18

3 4/9 = (3*9+4)/9 = 31/9 = (31*2)/(9*2) = 62/18

2) 9 1/2 = (9*2+1)/2 = 19/2 = (19*6)/(2*6) = 114/12

5 1/3 = (5*3+1)/3 = 16/3 = (16*4)/(3*4) = 64/12

6 3/4 = (6*4+1)/4 = 25/4 = (25*3)/(4*3) = 75/12

8 5/6 = (8*6+5)/6 = 53/6 = (53*2)/(6*2) = 106/12

3) 12 2/3 = (12*3+2)/3 = 38/3 = (38*15)/(3*15) = 570/45

7 3/5 = (7*5+3)/5 = 38/5 = (38*9)/(5*9) = 342/45

6 4/9 = (6*9+4)/9 = 58/9 = (58*5)/(9*5) = 290/45

4 2/15 = (4*15+2)/15 = 62/15 = (62*3)/(15*3) = 186/45
