When you graph decimals on a number line to compare them, the
greater number is farther to the right. You can also compare decimals
by looking at their place values. How?
Copy in your
notebook

3 STEPS FOR COMPARING & ORDERING DECIMALS
5.796 and 5.85
1. Write the decimals in a column, lining up the
decimal points.
5 .
5 .
7 9 6
8 5 0
2. If necessary, write zeros to the right of the decimals
so that all decimals have the same number of decimal
places.
3. Compare place values from left to right.
Since 8 > 7, 5.850 > 5.796
