4) a. 3/8 - 2/8 = 1/8
b. 14/60 + 9/60 - 255/60 = -232/60 = - 3 52/60 = -3 13/15
c. 22/3 - 55/8 = 176/24 - 165/24 = 11/24
d. 24/54 + 33/54 + 10/54 - 252/54 = -185/54 = -3 23/54

5) 1 1/4 + 2 4/5 = 5/4 + 14/5 = 25/20 + 56/20 = 81/20 = 4 1/20 kg

6) 1 - 1/3 = 3/3 - 1/3 = 2/3 kg

7) 1 - 4/5 = 5/5 - 4/5 = 1/5 hektare

8) 20 3/10 + 31 3/4 = 600/10 + 372/4 = 1.200/20 + 1.860/20 = 3.060/20 = 153 kg

9) 3/4 + 1 2/3 = 3/4 + 5/3 = 9/12 + 20/12 = 29/12 = 2 5/12 liter
