- [Instructor] We are
asked to select the diagram
-
that represents 1/6 times 1/4.
-
So why don't you pause this video?
-
Have a go at it before
we do this together.
-
Okay, before I even look at these choices,
-
I could think about what
this might look like.
-
So if I had a square unit,
-
I'm just gonna hand draw it so
it's a little bit shaky here.
-
So I could imagine having
1/6 on the left side
-
and then 1/4 on top.
-
So how would I do that?
-
So I would divide it into six
equal sections horizontally.
-
So I could do it like this.
-
So it could look something like this
-
where each of these is 1/6
and then I'm going to multiply
-
and maybe I would put
that maybe in that color
-
and then in the other direction
-
I would divide it into fourths.
-
So let's see, that's about half.
-
And then I will put those
in half to get fourths.
-
So 1/6 times 1/4.
-
And so the fourth, let me
do this in a light color
-
so it doesn't write over.
-
It would be that-
-
Well, lemme do it in the color
that you can actually see.
-
It might be all of that right over there.
-
And then their overlap
would be right over here.
-
So this would be 1/6 times 1/4
-
and that's actually 1/24
of this entire square.
-
So let's see.
-
Do I see anything that looks like that?
-
Let's see.
-
This first one looks like 1/4 times 1/4.
-
That's not right.
-
This one looks like 1/6
'cause this is 1/6 right here,
-
but it's 1/6 times 1/2
'cause in this direction
-
we're only split into two.
-
This one over here doesn't
look like what we did.
-
But if we turn it around and
if we do it the other way,
-
where if we divide it into
fourths on horizontally
-
and then into sixths vertically,
-
it looks a lot like choice C.
-
So if I divided into sixths here,
-
so if I had 1/4 times 1/6,
-
1/4 would be that entire row.
-
1/6 would be this entire column.
-
When you take their product,
you would get that shaded area,
-
which is exactly what
they did in choice C.
-
So this is 1/4 times 1/6,
-
and you get that shaded area.
-
So I like choice C.
