COMPARE & ORDER DECIMALS

Steps to Compare and Order Decimals

1. Rewrite the decimals vertically with the decimal points lined up.
2. Add zero place holders so that all numbers have the same
    number of digits.
3. Start with the greatest place value and put them in order.

Example:

4.3, 4.55, 4.09, 4.097

Rewrite:
4.300
4.550
4.090
4.097
Order from greatest to least.    4.550 is the greatest.
 (just look at the 550).
Answer: 4.55, 4.3, 4.097, 4.09

Try this one-

Which is smaller? 5.46 or 5.056

Line up the decimal points.
Add zero placeholders.

5.460
5.056
056 < 460
