a) 1-4/5 = 5-4/5 = 1/5
b) 2/3 - 1/5 =  10-3/15 = 7/15
c) 4/5 - 3/4 = 16-15/20 = 1/20
d) 19/5 - 2 = 38-20/10 = 18/10
e) 3+8/5 = 15+8/5 = 23/5
f) 3*2/7 - 1*1/3 = 6/7 - 1/3 =  18-7/21 = 11/21
g) 3/7 + 2/5 = 15+14/35 = 29/35
h) 3+2/5 - 1/4 =    60 + 8 + 5 /20 = 73/20
i) 4 - 4/5 + 8/5 = 4- 4+8/5 = 4- 12/5 = 20-12/5 = 8/5
j) 4/7 + 3/5 + 2 = 20 + 21 + 70 /35 = 111/35
