  • - [Instructor] We're asked to move the dot to 7/6

  • on the number line.

  • So pause this video.

  • I can move this dot right over here,

  • but I encourage you, pause the video,

  • and put your finger on where 7/6 would be

  • on the number line.

  • All right, now let's work on this together.

  • So what they're saying is,

  • is from zero to this point on the number line

  • right over there, that gets us to 1/6.

  • So each of these spaces are a sixth.

  • So we go zero, 1/6, 2/6,

  • 3/6, 4/6, 5/6,

  • 6/6, 7/6.

  • Let me make sure I got that.

  • So each of these are a sixth.

  • So we have one, two, three,

  • four, five, six, 7/6.

  • So that's 7/6 on that number line.

  • Now they have other ways of getting at the same idea.

  • For example, they say which point is at 9/4

  • on the number line?

  • And they ask us to choose one answer,

  • and we can look at the choices here.

  • So which choice shows 9/4 on the number line?

  • Pause this video and see if you can pick that.

  • All right, now let's look at each of these.

  • So it looks like in choice, in this first choice,

  • the space between zero and one

  • is split into one, two, three, four equal spaces.

  • So as we go from zero to this next line,

  • that's a fourth.

  • And that seems like it keeps going.

  • So this is 1/4, 2/4, 3/4, 4/4,

  • 5/4, 6/4, 7/4,

  • 8/4, 9/4 is here.

  • That's what we're looking for.

  • But the dot is not at 9/4.

  • It's at 10/4, 11/4, it's at 12/4.

  • So I don't like choice A.

  • Let's see, choice B.

  • Let's see what is, let's see,

  • we have divided the space between zero and one

  • into one, two, three,

  • four, five, six equal spaces.

  • So each of these are a sixth.

  • So to go from zero to one,

  • you've already gone 6/6, and then 7/6, 8/6, 9/6.

  • So this is 9/6, not 9/4.

  • And so let's look at this last choice.

  • I'm already feeling like it should be the answer, but.

  • We can see that the spaces are the same

  • as in our first choice, so these are each fourths.

  • Once again I know that because the space

  • between zero and one or any two whole numbers

  • is divided into four equal spaces.

  • So to go from zero to one, you go 4/4,

  • and then 5/4, 6/4,

  • 7/4, 8/4, and 9/4.

  • So choice C is definitely looking good.

  • Let's do one more example.

  • So here they say, what fraction is located

  • at Point A on the number line?

  • Pause this video and see if you can answer that.

  • All right.

  • So between the whole numbers,

  • how many spaces, equal spaces, do we have?

  • It looks like we have one, two, three,

  • four, five, six equal spaces.

  • So things are divided into sixths.

  • So 1/6, 2/6, 3/6,

  • 4/6, 5/6, 6/6,

  • which is equal to one,

  • and then 7/6.

  • So this is seven over six, just like that,

  • and we are done.
