To model multiplying fractions, you will cut the rectangle on one side horizontally and then shade. Then, cut the rectangle on a different side vertically and then shade. To determine the product (answer), count how many rectangles are shaded twice. This is your numerator. Last, multiply to find how many rectangles there are in all. This is your numerator. Choose the answer 8/15 for this question. On the next slide you will try one on your own.

• 8/15

• 1/15

• 2/15

• 3/15

Simplify the expression.

(3x - 9) + (-7x + 4)

• 4x - 13

• 10x + 5

• -4x + 13

• -4x - 5

What is the result when the expression (5x - 2) is subtracted FROM (-2x + 8)?
