What is the product of 12.3 and 2.56?

Explanation:
When multiplying decimals, you can multiply as whole numbers and then place the decimal point so that the total number of decimal places in the product equals the sum of decimal places in the factors. Here, 12.3 has one decimal place and 2.56 has two, for a total of three decimal places. Remove the decimals: 12.3 becomes 123 and 2.56 becomes 256. Multiply: 123 × 256 = 31488. Now put the decimal point three places from the right: 31.488. So the product is 31.488. The other options come from miscounting or misplacing the decimal point after multiplication.
