  • - [Instructor] We're told that each rectangle is a whole.

  • So this is a whole right over there,

  • that's one whole, and so this is two wholes.

  • Which expressions describe the shaded part of the picture?

  • And they've shaded in everything,

  • and they say choose two answers.

  • So pause this video and see

  • if you can answer that before we work on this together.

  • So before I even look at the choices,

  • there's different ways I could represent this.

  • I have, I've already talked about

  • that if each of these rectangles is a whole,

  • we have two of 'em, so I could say this is two wholes.

  • That's one way to represent it.

  • Another way to represent it is,

  • let's see each of the wholes is divided

  • into two equal sections so this

  • is a half right over there and this is another half.

  • This is a half and this is another half.

  • So total shaded in we have one,

  • two, three, four halves shaded in.

  • So we could also represent it as four halves.

  • Or instead of writing half out like that,

  • you could also represent a half like that 1/2,

  • that's another 1/2, that's another 1/2, that's another 1/2.

  • And how many of these halves do we have,

  • we have one, two, three, four.

  • So how can we write four halves,

  • well you can write it as 4/2.

  • So which expressions describe

  • the shaded part of the picture?

  • Well it's definitely not just one whole,

  • we have two wholes here so I'll rule that one out.

  • 4/2, yep we already thought about that one.

  • Four halves, yeah we thought

  • about that one as well so we're done.
