- [Instructor] We're told that the weights

of 11 different babies are recorded on the line plot below

and we see there is one, two, three, four,

Each weight was rounded to the nearest 1/8 of a pound.

All right, now where are the two heaviest babies?

and what is that number or what is that weight?

This is also nine and 1/4 of the way to 10,

so this is the same thing as nine and 1/4.

And then what's the second heaviest babies?

So the second heaviest baby is right over here

and we know that it is eight and a half pounds.

So what we really need to do is figure out

what is the difference between nine and 2/8

So we could set this up as a subtraction.

The difference is this length right over here.

And we could think about it in terms of eighths,

'cause each of these hash marks is an eighth,

We could also think about it in terms of fourths,
