Answer 1

a)19/21-4/7= 19/21 - 12/21 = 7/21 = 1/3

 b)7/8-12/32=  28/32 - 12/32 = 16/32 = 1/2 

 c)13/24-1/6= 13/24 - 4/24 = 9/24 = 3/8

d)9i3/8-3/4= 75/8 - 6/8 = 69/8 = 8 i 5/8

e)4i2/3-2i5/6=  14/3 - 17/6 = 28/6 - 17/6 = 12/6 = 2

f)2i3/10-7/20=  23/10 - 7/20 = 46/20 - 7/20 = 39/20 = 1 i 19/20

g)7i1/6-3/4= 43/6 - 3/4 = 86/12 - 9/12 = 77/12 = 6 i 5/12

 h)7i1/3-2i1/2=  22/3 - 5/2 = 44/6 - 15/6 = 29/6 = 4 i 5/6

i)4i3/10-1i4/5=  43/10- 9/5 = 43/10 - 18/10 = 25/10 = 5/2 = 2 i 1/2

j)5i1/4-1i2/3=  21/4 - 5/3 = 63/12 - 20/12 = 43/12 = 3 i 7/12

  k)4i5/6-1i3/4=  29/6 - 7/4 = 58/12 - 21/12 = 37/12 = 3 i 1/12       

Answer 2

a)19/21-4/7=19/21-12/21=7/21=1/3

b)7/8-12/32=28/32-12/32=16/32=1/2

c)13/24-1/6=13/24-4/24=9/24 

d)9i3/8-3/4=8 i 11/8- 6/8=8 i 5/8            

e)4i2/3-2i5/6=4i 4/6-2 5/6=1 5/6

f)2i3/10-7/20=1i 26/20-7/20=1i 19/20  

g)7i1/6-3/4=6i 14/12-3i 9/12=3 5/12  

h)7i1/3-2i1/2=6i 8/6-3i 3/6=3 5/6   

i)4i3/10-1i4/5=3i 13/10-1i 8/10=2i 5/10=2i 1/2  

j)5i1/4-1i2/3=4i 15/12-1i 8/12=3i 7/12   

k)4i5/6-1i3/4=4i 10/12-1i 9/12=3i 1/12
