Video transcript

we're told that each rectangle is a hole so this is a hole all right over there that's one hole and so this is two holes which expressions describe the shaded part of the picture and they've shaded in everything and they say choose to answer 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've I've already talked about that if each of these rectangles is a hole we have two of them so I could say this is two holes that's one way to represent it another way to represent it is let's see each of the holes is divided into two equal sections so this is 1/2 right over there and this is a another half this is 1/2 and this is another 1/2 so total shaded in we have 1 2 3 4 halves shaded in so we could also represent it as 4 halves or instead of writing 1/2 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 1 2 3 4 so how can we write 4 halves well you can write it as 4 over 2 so which expressions describe the shaded part of the picture was definitely not just one hole we have two holes here so I'll rule that one out 4 has yep we already thought about that one 4 halves yeah we thought about that one as well so we're done
