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.

- 2. Which number is greater? Compare 0.3 and 0.25 Rule for comparing: Always start and the left and move right – compare values of digits as you move.
- 3. Compare 0.3 and 0.25 Step 1: Start at the number on the left – in this case 0 Both digits are equal Step 2: Move to the next place value (tenths) The digits are different 3 > 5 Therefore, 0.3 > 0.25
- 4. Compare 0.217 and 0.271 Step 1: Start at the place value on the left – in this case it’s 0 Both digits are equal Step 2: Move to the next place value – both digits are 2 (equal) Step 3: Move to the next place value – the digits are different 7 > 1 Therefore, 0.271 > 0.217
- 5. You try it! Compare the decimals. Write >, <, or = 1) 0.345 0.354 2) 47.58 45.78 3) 13.344 13.433 4) 583.583 583.583 5) 565.659 565.656
- 6. Order Decimals Ordering decimals follows the same rules as ordering whole numbers Line up the digits and the decimal point and compare the numbers
- 7. Example Order 0.91 0.9 0.87 Line up the decimals 0.91 0.9 0 0.87 Uh-oh! I have an open place value! No problem! Just put a 0 there to fill its place --- it DOES NOT change the value of the decimal.
- 8. Example 1 continued… Compare the numbers 0.91 0.9 0 0.87 0.87 is the least, then 0.90, and 0.91 is the greatest
- 9. Example 2 Order 0.057 0.781 0.08 Line up the decimals 0.057 0.781 0.08 0 Uh-oh! I have an open place value! No problem! Just put a 0 there to fill its place --- it DOES NOT change the value of the decimal.
- 10. Example 2 continued… Compare the numbers 0.057 0.781 0.08 0 0.057 is the least, then 0.080, and 0.781 is the greatest
- 11. You try it! Order each set from least to greatest 0.547 0.541 0.5 0.81 0.589 0.817 0.41 0.83 0.58
