• - [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 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.

• 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.
