Answer 1

12 7/12 - 11/12= 11 19/12 - 11 /12 = 11 8/12 = 11 4/6 = 11 2/3

7 1/4-3 3/4=6 5/4 - 3 3/4 = 3 2/4 = 3 1/2

12 4/45 - 9 27 /45 =11 49/5 - 9 27/45 = 2 22/45

 

12 7 /12-11/12=11 19/12 - 11/12 = 11 8/12 = 11 4/6 = 11 2/3

10 5/8- 7 7/8=9 13/8 - 7 7/8 = 2 6/8 = 2 3/4

82 7/60 - 31 31 /60 =81 67/60 - 31 31/60 = 50 36/60 = 50 6/10 = 50 3/5

19 3/7- 8 19/7=16  24/7 - 8 19/7 = 8 5/7

30 11/18 - 17/18=29 29/18 - 17/18 = 29 12/18

20 5 /9 - 10 7/9=19 14/9 - 10 7/9 = 9 7/9

102 4/39- 61 25/39=101 43/39 - 61 25/39 = 40 18/39

36 3/10- 16 = 20 3/10

 

 od calych zabierasz cale, od ulamkow - ulamki...

ulamki niektore rozkladane: 12 = 11 i 45/45; 10 = 9 i 8/8

stad bierzesie :)

 

mysle, ze zrozumiesz :)
