9. For each of the following n ultiplication facts, give two division facts :
(i) (- 135) * 5 = – 675
(ii) (-9) (- 10) = 90 (iii) (-20) x (+ 15) = – 300
(iv) (1560) (-1) = – 1560
(v) 1*(-18) = – 18 (vi) (-1) x1= -1
Calculate and verify using the distributive law over addition :
(i) – 12 x [(- 6) + 3] (ii) 110 x [(-2) + (-3)
(iii) 45 % (18 + (-8)]​
