Find the products: (i) 6.3204 * 100(ii) 0.069 * 10000
Answer: D
Multiplying by a power of ten moves the decimal point right by as many places as the power has zeros.
(i) \[ 6.3204 \times 100 = 632.04 \]
(ii) \[ 0.069 \times 10000 = 690 \]
In the second the point moves four places but only three digits are available, so a zero is written in to fill the gap: 0.069 becomes 0690, that is 690.
