  • This right over here would be about 8/8.
  • So this looks about 5/8.
  • And then they tell us that this other one that's below my screen right over here is 1 and 3/4.
  • So they tell us that this is 1 and 3/4 units long.
  • 1 and 3/4 is also the same thing as 7/4.
  • So I somehow need to-- let's see, what are my tools?
  • What are the tools available to me?
  • Well I can cut my starting block into a certain number of pieces.
  • And then I'm going to copy that starting block over here for block 1, and I'm going to try to match it to this goal block.
  • And then I'm also going to copy it for block 2, to match that second goal block.
  • So I'm going to try to get something that's 5/8, and I'm also going to try to get something that's 1 and 3/4.
  • Now 3/4 is the same thing as 6/8.
  • And the reason why I care about eighths is eighths is a smaller unit.
  • So if I can convert the starting block into eighths, then I can copy it enough times to get exactly to 5/8, and exactly to 1 and 3/4, which is the same thing as-- 3/4 is the exact same thing as 6/8.
  • So let's get our starting block into eighths.
  • So if we're starting with 2 wholes, if we're starting with 2 units long-- So if I cut it once, now this is a whole unit.
  • Now if I cut a whole, now if I cut it twice, so now if I cut 4 times, so I've cut my original block into 4 times.
  • So now this right over here is half a unit.
  • And actually, if I want to convert it into eighths I need to cut it 16 times.
  • So let me do that.
  • 15, 16.
  • So I cut 2 units into 16 equal pieces.
  • Or I guess this is 1/16 of 2, so that is going to be an eighth.
  • And now I just have to multiply this the appropriate number of times.
  • This right over here is 5/8.
  • This is 1/8.
  • So let me copy this, 1, 2, 3, 4, 5.
  • So that is 5/8.
  • And then here, I need to do 1 and 3/4.
  • Remember, 1 and 3/4 is the same thing as 7/4.
  • It's 4/4 plus 3/4, which is 7/4.
  • 7/4 is the same thing as 14/8.
  • So this right over here is 1/8, I just need to make 14 of these.
  • 2, 3, 4, 5, 6, 7, 8.
  • Actually, let me show you what I'm doing.
  • 9, 10, 11, 12, 13, 14.
  • And there we go.
  • That's exactly the same length as goal block 2.
  • This is 14/8.
  • 14/8 is the exact same length as this.
  • 14/8 is the same thing as 7/4, which is the same thing as 1 and 3/4.
  • This is 5/8, which is the same thing as 5/8.
  • So let's check our answer.
  • And we got it right.
