The document discusses comparing and ordering decimals. It explains that decimals can be compared using the symbols > or <, and that annexing zeros to the right of a decimal does not change its value, which is useful for ordering decimals from least to greatest. As an example, it lists the decimals 14.95, 15, 15.01, and 15.8 in order from least to greatest. It also provides additional decimal comparisons to use >, <, or = symbols.

 Which city has the longest subway system?
Explain

3.  Comparing decimals is similar to
comparing whole numbers. You can
use the symbols > or < to indicate
that one quantity is greater than or
less than the other.

4.  Decimals that name the same number are
called equivalent decimals.
◦ Examples are 0.8 and 0.80

5.  When you annex zeros to the
right of the last digit in a decimal,
the value of the decimal does not
change. Anexing zeros is useful
when ordering a group of
decimals.

6.  Order 15, 14.95, 15.8 and 15.01 from least to
greatest.
 The order from least to greatest is 14.95, 15,
15.01 and 15.8

7.  Use >, <, or = to compare each pair of
decimals
