Simplify the following fraction expressions. Show all of your work.

Draw diagrams to represent each fraction.

**Diagram expression with 2 equal sized rectangles: Left Rectangle + Right Rectangle. Rectangle A, 4 rows, with 3 shaded. Rectangle B, 3 columns, with 2 shaded.**Now change the diagram so that each whole is divided into equal portions.

**Changes: Left rectangle, divided into 3 columns, 9 out of 12 shaded. Right column, divided into 4 rows, 8 out of 12 shaded.**
