b). -5/12

c). 5/4

e). 12/18

f). 111/12

Penjelasan dengan langkah-langkah:

a). 2/3 + 1/2

= 4/6 + 3/6

=  7/6

b). - 1/4 x 1 2/3

= -1/4 x 5/3

= -5/12

c). 3 3/4 - 2 1/2

= 15/4 - 5/2

= 15/4 - 10/4

= 5/4

d).  3/9 -(- 1/3)

=3/9 + 1/3

= 6/18 + 6/18

= 12/18

e). - 5/6 - 4/5

=  -25/30 - 24/30

= -49/30

f). - 3 1/3 - 5 1/4 + 1/6

= - 10/3 - 21/4  + 1/6

=  -80/24 - 126/24 + 4/24

= 222/24 == 111/12
