1)50 13/22 – (4 1/6 + 25 9/11)=20 20/33

1.4 1/6 + 25 9/11=29 65/66

2.50 13/22 – 29 65/66=20 20/33

2)27 2/9 + (16 43/45 – 5 11/15)=38 4/9

1.16 43/45 – 5 11/15=11 2/9

2.27 2/9 + 11 2/9=38 4/9

3)(29 11/18 + 14 7/12) – 5 13/24=38 47/72

1.29 11/18 + 14 7/12=44 7/36

2.44 7/36 – 5 13/24=38 47/72

4)59 25/64 – (32 3/16 + 4 1/64) + 3 1/8=20 1/16

1.32 3/16 + 4 1/64=36 13/64

2.36 13/64 + 3 1/8=39 21/64

3.59 25/64 – 39 21/64=-20 1/16

_______________________________

5)(40 61/80 – 7 17/20) + 25 3/40 – 14 3/10

1.40 61/80 – 7 17/20=32 73/80

2.32 73/80 + 25 3/40=57 79/80

3.57 79/80 – 14 3/10=43 11/16

6)37 29/36 – (4 5/18 + 1 31/48) – 5 3/4=

1.4 5/18 + 1 31/48=5 133/144

2.5 133/144 + 4 5/18=10 29/144

3.10 29/144 – 5 3/4=4 65/144
