Răspuns:

Explicație pas cu pas:

25/8 - 27/24 - 37/37 = 75/24 - 27/24 - 1 = 48/24 - 24/24 = 24/24 = 1

___________

18/18 - 15/30 + 9/8 = 1 - 1/2 + 9/8 = 1/2 + 9/8 = 4/8 + 9/8 = 13/8

___________

1/3 + 1/4 + 1/5 + 2/3 + 3/4 + 4/5 = (1/3 + 2/3) + (1/4 + 3/4) + (1/5 + 4/5)

= 3/3 + 4/4 + 5/5 = 1 + 1 + 1 = 3

___________

5/2 + 7/3 + 11/6 - 3/2 - 4/3 - 5/6 = (5/2 - 3/2) + (7/3 - 4/3) + (11/6 - 5/6)

= 2/2 + 3/3 + 6/6 = 1 + 1 + 1 = 3
