8/15/11

Today we began multiplying decimals.  We also worked on finding where a decimal would be located on a number line.  When multiplying decimals, we should multiply as if the decimals are not there and then count how many numbers there are after the decimal in the problem.  That is how many places after the decimal there should be in your answer.  Example:   2.02 * 1.36 = ___________  There are 2 places after the decimal in the first factor and 2 places after the decimal in the second factor, so there should be a total of 4 places after the decimal in your answer.  You should multiply 202 times 136 and get 27472, then you would move the decimal 4 places so your answer would be 2.7472.  I hope this helps with the homework.
