Multiplication of Decimals
Multiply as whole numbers, then place decimal point. Count total decimal places in both numbers. Put same number in product. Example: 2.3 ร 1.5: 23 ร 15 = 345. Total decimal places = 1+1 = 2. Answer: 3.45. Multiplying by powers of 10: move decimal right (ร10 โ right 1, ร100 โ right 2).
