Transcript Comparing Whole Numbers

Comparing and Ordering Whole
Numbers
Example 1: Compare 76 and 67
Write:
67 < 76
76 > 67
Say:
67 is less than 76
76 is greater than 67
Remember, the mouth of the symbol (> or
<) always opens to the greater number.
Example 2: Blanca Peak is 14,345 feet
above sea level. Crestone Peak is
14,294 feet above sea level. Which
peak is taller?
1. Line Up the place
values by lining up the
ones.
14,345
14,294
2. Begin at the left.
Find the first place
where the digits are
different
14,345
14,294
different
same
3. Compare the value
of the digits.
300 > 200
So
14,345 > 14,294
Caution!!!!!
Be sure to line up digits with the same place value when comparing or
computing.
Example: You score 108,464 points. Your friend scores 97,996. The
higher score wins. Who wins?
Lined Up Incorrectly
108,464
97,996
Lined Up Correctly (at the ones place)
108,464
97,996
Note: When one whole number has
more digits than the other, it is greater.
Write: 108,464 > 97,996 or 97,996 < 108,464
Let’s Try!
Compare using <,>, or =.
• 534 __ 509
• 45,943 __ 45,494
• 904,109,005 __ 940,109,005
• 174,903,845,182 __ 174,903,845,182
Order the following numbers from greatest to
least.
61,565; 71,649; 75,367
1. Line up the
numbers at the ones
place.
61,565
71,649
75,367
2. Begin to compare
at the left.
61,565
71,649
75,367
70,000 > 60,000
So 61,565 is the least.
3. Continue. Find the
first place where the
digits are different.
71,649
75,367
5,000 > 1,000
So 75,367 > 71,649
75,367 ; 71,649; 61,565 (greatest to least)
Let’s Try!!
• Order from least to greatest…
• 2,756,833; 2,756,820; 2,756,338
• Order from greatest to least…
• 90,654; 87,223; 87,954; 90,556
