Answer 1

Answer:

i) 1/15

ii) 2/21

iii) -1/7

iv) -23/9

Step-by-step explanation:

Hii Mate ^_^

i) (2/3) - (3/5)

  = (10/15) - (9/15)

  = (10-9)/15

  = 1/15

ii) (-4/7) - (2/-3)

   = (-4/7) - (-2/3)

   = -(4/7) + (2/3)

   = (2/3) - (4/7)

   = (14/21) - (12/21)

   = (14-12)/21

   = 2/21

iii) (4/7) - (-5/-7)

    = (4/7) - (5/7)

    = (4-5)/7

    = -1/7

iv) -2 - (5/9)

    = -(18/9) - (5/9)

    = (-18-5)/9

    = -23/9
