Answer 1

Answer:

Step-by-step explanation:

1. a] -2/3 × 3/5 + 5/2 - 3/5 × 1/6

By Distributive property = - 3/5 ×[2/3 + 1/6] + 5/2

                                       = -3/5 × [4/6 + 1/6] + 5/2

                                       = [-3/5 × 5/6] + 5/2

                                       = -15/30 + 5/2

                                       = -15/30 + 75/30

= 60/30 = 2

b] 2/5 × -3/7 - 1/6 × 3/2 + 1/14 ×2/5

By Distributive property = 2/5 [-3/7 + 1/14] -1/6 × 3/2

= 2/5 [ -6/14 + 1/14] - 1/6 × 3/2

= [2/5 × -5/14]  [-1/6 × 3/2]

= -1/7 - 3/12

= -12/84 -21/84

= -33/84

= - 11/28

2. a] Additive inverse of 2/8 is -2/8.

b] Additive inverse of -5/9 is 5/9.

c] Additive inverse of -6/-5 = 6/5 [minus and minus cancelled] is -6/5
