Explicație pas cu pas:

6/8 - 10/25 = 3/4 - 2/5 = 15/20 - 8/20 = 7/20

_________

10/100 - 2/40 = 1/10 - 1/20 = 2/20 - 1/20 = 1/20

__________

60/90 - 40/150 = 2/3 - 4/15 = 10/15 - 4/15 = 6/15 = 2/5

__________

21/12 - 25/30 = 7/4 - 5/6 = 21/12 - 10/12 = 11/12

__________

3 - 5/10 - 2/6 - 3/18 = 3 - 1/2 - 1/3 - 1/6 = 18/6 - 3/6 - 2/6 - 1/6 = 12/6 = 2

__________

13/17 - 1313/1717 = 13/17 - 13/17 = 0

1313 =13 x 101

1717 = 17 x 101

_____________

44/33 - 222/555 - 1111/6666 + 3/30

4/3 - 2/5 - 1/6 + 1/10 = 40/30 - 12/30 - 5/30 + 3/30 = 26/30 = 13/15
