  • 1.3/4 - 2/4 = 1/4
    2.3/4 - 2/5 = 15/20 - 8/20 = 7/20
    3.1 3/4 - 2/5 = 7/4 - 2/5 = 35/20 - 8/20 = 27/20 = 1 7/20
    4.2 3/4 - 1 2/5 = (2 - 1) 3/4 - 2/5 = 1 7/20
    5.6 - 2/3 = 5 3/3 - 2/3 = 5 1/3
    6.5 3/4 - 2 = (5 - 2) 3/4 = 3 3/4
    7.2,47-2,1= 2,47-2,10 = 0,37
    8. 19,7 - 1,25 = 19,70 - 1,25 = 18,45
    9.40,1 - 29,8 = 11,1 - 0,8 = 10,3

    Segitu aja gan. Maaf ya kalau salah atau kurang lengkap. :)
