Speaker

All right mathematicians, welcome back. I'm back with your next challenge. Last time we were talking about fractions, and we were saying we defined the whole…

[The speaker traces the outline of the square with her finger.]

…as the outside of the entire tangram put together as a square, our original square sheet of paper. This time, my question for you is, now what are each of the individual pieces of my puzzle worth if one…

[She places a red square with a ‘1’ over the green square.]

…is actually now defined as this square? So if this is one, my parallelogram…

[She points to the bottom green triangles with writing: 1/16.]

…can no longer be 1/16 combined with 1/16, which is 1/8. It has to be worth something to... something else. So back to you mathematicians, to work this out. If this square…

[She points to the red square.]

…is defined as one whole, what are all the other pieces of my tangram now described as? Over to you! Have fun with your sweaty brains.

[Text over a blue background: Over to you!]
