2.5 Homework assignment on part-whole diagrams Note: I have set this up in Microsoft Word so that if you are using Word, you should be able to type directly into the diagrams, so you can just type your answers rather than hand-drawing and scanning. If you are using open office, you may find that you can't type into the diagrams, and in that case you will probably need to hand-draw the diagrams and scan them in.
