Answer 1

- 4 5/9 + 8 2/9 + (-1 1/9) =
= -4 5/9 + 7 11/9 - 1 1/9 =
= 3 6/9 - 1 1/9 = 2 5/9

- 2 + (-6 3/4) + ( - 5 1/4) =
= -2 - 6 3/4 - 5 1/4 = -2 - 12 = -14

- 1/2 - 1/3 - 1/4 =
= -6/12 - 4/12 - 3/12 = -13/12 = -1 1/12

-5 1/8 + 3 3/16 - 10 5/32 =
= -5 4/32 + 3 6/32 - 10 5/32 =
=-4 36/32 + 3 6/32 - 10 5/32 = -1 30/32 - 10 5/32 = -11 35/32 = -12 3/32

2 5/8 + ( - 3 3/16) + (-1/4) =
= 2 10/16 - 3 3/16 - 4/16 =
= 2 10/16 - 3 7/16 = 2 10/16 - 2 23/16 = -13/16

-81/3 + ( - 2 1/4) + ( - 4 1/5) =
= -27 - 2 5/20 - 4 4/20 = -27 - 6 9/20

zad 2

2/3 + 0,5 = 
= 2/3 + 1/2 = 4/6 + 3/6 = 7/6 = 1 1/6

3 1/5 + 0,72 =
= 3,2 + 0,72 = 3,92

6 6/7 + 0.07 =
= 6 6/7 + 7/100 = 6 600/700 + 49/700 = 6 649/700

5 1/8 + 7,125 =
= 5,125 + 7,125 = 12,25

30/25 - 1,2 = 1,2 - 1,2 = 0

30,25 - 1/2 =
= 30,25 - 0,5 =29,75

4,6 - 2 2/3 = 
4 6/10 - 2 2/3 = 4 3/5 - 2 2/3 = 4 9/15 - 2 10/15 = 
= 3 24/15 - 2 10/15 = 1 14/15

8,625 - 2 3/8 = 8,625 - 2,375 = 6,25
