  • 3 1/2 - 3/10= 7/2 - 3/10 = 35-3 /10 = 32/10 = 3,2
    3 3/4 - 6/12= 15/4 - 6/12 = 46-6 /12 = 39/12 = 3,25
    2 2/3 - 3/6= 8/3 - 3/6 = 16-3 /6 = 13/6 = 2,16
    2 5/7 - 6/14= 19/7 - 6/14 = 38-6 /14 = 32/14 = 2,28
    3 2/3 - 2/9= 11/3 - 2/9 = 32-2 /9 = 31/9 = 3,44
    3 1/2 - 5/6= 7/2 - 5/6 = 21-5 /6 = 16/6 = 2,66
    2 1/4 - 3/8= 9/4 - 3/8 = 18-3 /8 = 15/8 = 1,87
    2 1/5 - 5/10= 11/5 - 3/10 = 22-3 /10 = 19/10 = 1,9
