Answer
Explanation
(i) 21693 × 14 = 303702. Sum of decimal places = (4 + 1) = 5. So 2.1693 × 1.4 = 3.03702. (ii) 4 × 4 × 4 × 40 = 2560. Sum of decimal places = (1 + 2 + 3) = 6. So .4 × .04 × .004 × 40 = .002560. (iii) 666 × 666 × 66 = 29274696. Sum of decimal places = (2 + 1) = 3. So 6.66 × 66.6 × 66 = 29274.696.
