1) The document discusses how to compare and order decimals less than one. It explains that when comparing decimals, you look at the digits from left to right and the decimal with the greater digit value in the first place of difference is larger. 2) Examples are provided of comparing decimals like 0.3 and 0.25 by looking first at the tenths place and seeing that 3 is greater than 5, making 0.3 the larger number. 3) Ordering decimals follows the same process, lining up the digits and decimal points before comparing place values from left to right to determine the order from least to greatest.
