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

Text Solution

Verified by Experts

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`
