Respuesta:

Explicación paso a paso:

3/4- 6/9 =  (27 - 24)/36 = 3/36 Sacamos Tercia queda 1/12

4/5 + 2/7=  (28 + 10)/35 = 38/35

6/8- 2/9=  (54 - 16 )/72 = 38/72 Sacamos mitad queda 19/36

5/6+ 3/4= (10 +9)/12 = 19/12

7/9- 3/5=  (35 - 27)/45 = 8/45

3/5+ 4/6=  (18 + 20)/30 = 38/30 sacamos mitad queda 19/15
