Hi, I think Ron's and Gail's comments are great. I'd like to add a visual approach to helping you get the idea across. This approach is based upon an area model of multiplication. Let's look at 1/2 x 1/3 Start with a rectangle. Let it be the "whole." ----------- | | | | | | | | ----------- Divide this whole in half. The dimensions of the two resulting rectangles are 1/2 x 1. ----------- 1/2 | | |___________| | | 1/2 | | ----------- Now divide this whole in thirds as shown. The dimensions of the 6 resulting rectangles are 1/2 x 1/3. 1/3 1/3 1/3 ----------- 1/2 | | | | Each rectangle represents 1/6 of the whole. |___|___|___| So, | | | | 1 1 1 1/2 | | | | --- x --- = --- ----------- 2 3 6 Hope this helps. -Jeanne, for the T2T service
