Teaches basic steps for multiplying decimals. Solves problem (4.2 X 5.9) by removing the decimal and working as a whole number. Once solved, shows how to determine the decimal place in the answer by counting the digits behind the decimal in the origi...nal problem. Also shows how to round decimal into a whole number to see if answer is correct. Then shows how to solve a problem with no whole number (0.3 X 0.2). Once answered shows how to add zero to whole the whole number place and how to convert to a fraction to check answer.[more]
