Find the product:
(i) 9/2 × (-7/4)    (ii) 3/10 × (- 9)
(iii) -6/5 × 9/11   (iv) 3/7 × (-2/5)
(v) 3/11 × 2/5    (vi) 3/(-5)× -5/3

Solution:

We will be finding the product of numerator and denominator to get the results of the given products.

(i) 9/2 × (- 7/4) = [(9 × (- 7)]/(2 × 4) = - 63/8

(ii) 3/10 × (- 9) = (3/10) × (- 9/1) = [(3 × (- 9)]/(10) = - 27/10

(iii) - 6/5 × 9/11 = (- 6 × 9)/(5 × 11)= - 54/55

(iv) 3/7 × (-2/5) = [3 × (- 2)]/(7 × 5) = - 6/35

(v) 3/11 × 2/5 = (3 × 2)/(11 × 5) = 6/55

(vi) 3/(- 5) × (- 5/ 3)= [3 × (- 5)]/(- 5 × 3)= -15/(-15) = 1
