    [QUOTE=maddiexoxo;775257]. Model the following, showing any necessary calculations.
    a) 2/5 x 2/3 (using a rectangular array)[quote]
    Draw a 5 by 3 array of dots. That will give a total of 15 dots. Draw a vertical line after the second dot horizontally. Draw a horizontal line below the dot vertically. Now count the number of objects inside small rectangle formed by those two lines. The product is that number divided by 15.

    b) 2 = 9/4 (using circles)
    Draw six circles, three on the left, three on the right. On the left color in two of the circles and 1/4 of the third circle. On right, divide all three circles into quarters and color 9 of those quarters.

    c) 1 + 1 2/3 (using a number line subdivided according to the LCD)
    What is the LCD for this problem?

    d) 6/10 = 3/5 (using rectangles)
    e) 0.3 = 0.30 (using decimal squares

    explain please and thank you. even if you can only help me with one or two
