Question

Using distributivity, find : (i) [7/5 × ( -3/12)] + [7/5 + 5/12]
(ii). [ 9/16 × 4/12 ] + [9/16 × (-3/9)]​

Answer 1

Answer:

(i) [7/5 x (-3/12)] + [7/5 x 5/12]

  = 7/5 x (-3/12 + 5/12)

    = 7/5 x 2/12

     = 14/60

     = 7/30

(ii) [9/16 x 4/12] + [9/16 x (-3/9)

  = 9/16 x (4/12 + -3/9)

 = 9/16 x (4/12 - 3/9)

  = 9/16 x (12/36 - 12/36)

   = 9/16 x 0

     = 0
