BEST ANSWER :

1 (4)/(5) / (2)/(3) - 1 (5)/(7)

$(7 + 4)/(7) / (2)/(3) - 1 (5)/(7) \\ (11)/(7) / (2)/(3) - 1 (5)/(7) \\ (11)/(7) / (2)/(3) - (7 + 5)/(7) \\ (11)/(7) / (2)/(3) - (12)/(7) \\ (11)/(7) * (3)/(2) - (12)/(7) \\ (11 * 3)/(7 * 2) - (12)/(7) \\ (33)/(7 * 2) - (12)/(7) \\ (33)/(14) - (12)/(7) \\ (33)/(14) - (12 * 2)/(14) \\ (33)/(14) - (24)/(14) \\ (33 - 24)/(14) \\ (9)/(14)$
