Example 1: Compare 76 and 67Example 1: Compare 76 and 67

Write:Write: Say:Say:67 < 76 67 is 67 < 76 67 is less than less than 767676 > 6776 > 67 76 is 76 is greater than greater than 6767

Remember, the mouth of the symbol (> Remember, the mouth of the symbol (> or <) always opens to the greater or <) always opens to the greater number.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.

2. Begin at the left. Find the first place where the digits are different

3. Compare the value of the digits.

14,34514,294

14,34514,294

different

same

300 > 200

So14,345 > 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 Lined Up Correctly (at the ones place)

108,464 108,46497,996 97,996

Note: When one whole number hasmore 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.

2. Begin to compare at the left.

3. Continue. Find the first place where the digits are different.

61,56571,64975,367

61,56571,64975,367

70,000 > 60,000So 61,565 is the least.

71,64975,367

5,000 > 1,000So 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
