- [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.
