Answer 1

a) 1/2 - 3/6 = 1/2 - 1/2 = 0 

 1/2 - 3/8 = 4/8 - 3/8 = 1/8 

 4/5 - 19/25 = 20/25 - 19/25 = 1/25 

 11/18 - 5/9 = 11/18 - 10/18 = 1/18 

b) 2/3 - 1 4/5 = 2/3 - 9/5 = 10/15 - 27/15 = -17/15 = - 1 2/15

 1 2/6 - 2/3 = 8/6 - 2/3 = 4/3 - 2/3 = 2/3 

 2 1/4 - 1 6/8 = 9/4 - 14/8 = 9/4 - 7/4 = 2/4 = 1/2

 3 1/3 - 2 10/15 = 10/3 - 40/15 = 10/3 - 8/3 = 2/3 

c) 9 1/2 - 3 5/8 = 19/2 - 29/8 = 76/8 - 29/8 =  47/8 = 5 7/8

 5 1/10 - 4 3/5 = 51/10 - 23/5 = 51/10 - 46/10 = 5/10 = 1/2 

 2 1/21 - 1 5/7 = 43/21 - 12/7 = 43/21 - 36/21 = 7/21 = 1/3 

 1 1/5 - 39/50 = 6/5 - 39/50 = 60/50 - 39/50 = 21/50 

d) 2 7/9 - 1 1/6 = 25/9 - 7/6 = 50/18 - 21/18 = 29/18 = 1 11/18

 3 4/15 - 1 11/30 = 49/15 - 41/30 = 98/30 - 41/30 = 57/30 = 1 27/30

 2 7/30 - 1 17/20 = 67/30 - 37/20 = 134/60 - 111/60 = 23/60 

4 1/100 - 2 3/50 = 401/100 - 103/50 = 401/100 - 206/100 = 195/100 = 1 95/100 =   119/20

1 1/5-39/50=6/5-39/50=60/50-39/50=21/50

d) 2 7/9- 1 1/6=25/9-7/6=50/18-21/18=29/18

3 4/15-1 11/30=49/15-41/30=98/30-41/30=57/30

2 7/30-1 17/20=67/30-37/20=134/60-112/60=22/60

4 1/100-2 3/50=401/100-103/50=401/100-206/100=195/100
