These numbers are ordered from
least to greatest: 142, 238, blank, blank, 688, blank, 968. Use the numbers 544, 355, and 722
to fill in the gaps.
We know that these numbers are
ordered from least to greatest. That means we’ll be moving from
smallest to largest. And we have three spaces to fill
in. The first two spaces fall between
238 and 688. From our list, which one of these
three values is larger than 238 and smaller than 688? Well, 722 is larger than 688. Seven hundreds is more than six
hundreds. And that means that 722 can go in
between 688 and 968. 722 fills in our third space.
Back to these two, how do we know
what order 544 and 355 will go in? We look at their largest place
value. We look at the hundreds place. 544 has a five in the hundreds
place. 355 has a three in the hundreds
place. Because three is smaller than five,
355 comes first on our list of numbering things from least to greatest. And that leaves us with 544
By ordering our values from least
to greatest, we saw that the first blank would be 355, the second blank would be
544, and the third blank would be 722.
