    4/7+5/11+5/7

    5/8+2/11+9/11

    17/24+5/12-11/24

    11/12+1/6-5/24

    5/6-5/7+1/6-1/7)..7/10 + 1/10 = 8/10 = 4/5

    (2)..5/9 + 4/9 = 9/9 = 1

    (3)..8/15 + 3/15 = 11/15

    (4)..9/14 + 3/14 = 12/14 = 6/7

    (5)..3/5 + 8/5 = 11/5

    (6)..4/15 - 3/15 = 1/15

    (7)..7/8 - 5/8 = 2/8 = 1/4

    (8)..5/3 - 2/3 = 3/3 =1

    (9)..7/8 - 4/8 = 3/8

    (10)..1314/2010- 520/2010 = 794/2010 = 397/100

    4/5-(1/4+2/5)

    1-1/4-3/4

    5/7+5/9+2/7+4/
