We want to identify the whole number
plotted on the number line.
So, the key to doing
these types of problems
is to identify the scale
used for each number line.
Notice, on this first number line,
from zero to 1,000 is divided up into
one, two, three, four equal parts.
So, 1,000
divided by four would tell us
what each tick mark represents.
Well, 1,000 divided by
four is equal to 250.
So, each tick mark represents 250.
So, here, we'd have 250,
here we'd have 500,
here we'd have 750, and then 1,000.
So, for this example, this point
represents the whole number
750 on the number line.
Looking at the second
example, this is marked
from 5,900 to 6,000,
would be 100.
And this interval is divided into
one, two, three, four, five equal parts.
Well, 100 divided by five is equal to 20.
So, each tick mark represents 20.
So, starting at 5,900, we'd have 5,920,
5,940,
5,960 here,
5,980,
6,000,
6,020,
6,040 and so on.
So, the number 5,960 is
plotted here on the number line
and here we have 6,040
plotted on the number line.
Let's take a look at one more example.
From 10,950
to 10,970
would be 20.
And this interval of 20 is divided into
one, two, three, four equal parts.
20 divided by four is equal to five.
So, each tick mark represents five.
Here we'd have 10,955,
here we'd have 10,960,
and here we have 10,965,
followed by 10,970.
So, 10,965
is the whole number plotted
on this number line.
