Answer» (i) 54 x 99 L.H.S = 54 – 1 = 53 R.H.S = 99 – 53 = 46 ∴54 x 99 = 54 – 1/99 – 53 = 5346 (ii) 214 x 999 L.H.S = 214 – 1 = 213 R.H.S = 9 99 – 213 = 786 ∴ 214 x 999 = 214 – 1/999 – 213 = 213786 (iii) 47 x 999 L.H.S = 047 – 1 = 046 R.H.S = 999 – 046 = 953 ∴ 47 x 999 = 047 – 1/999 – 046 = 046953 = 46953 (iv) 342 x 99999 L.H.S = 00342 – 1 = 00341 R.H.S = 99999 – 00341 = 99658 ∴00342 x 99999 = 00342 – 1 /99999 – 00341 = 0034199658 (v) 73 x 9 L.H.S = 73 – 1 = 72 R.H.S = 9 – 72 ∴ 73 x 9 = 73 – 1/9 – 72 = 72/9 – 72 = 729 – 72 = 657 (vi) 467 x 99 L.H.S = 467 – 1 = 466 R.H.S = 99 – 466 ∴ 467 x 99 = 467 – 1/99 – 466 = 466/99 – 466 = 46699 – 466 = 46233 |
