### 4.2Comparing and Ordering Decimals

How do we compare numbers

• < Less Than
• > Greater Than
• = Equal to
• We look at place value

### Review

• How do we order numbers
• decide if we are ordering greatest to least or least to greatest
• Compare two numbers at a time
• Place in proper order

LEFT Hand  LESS THAN <

• RIGHT HAND  GREATER THAN >
• BOTH HANDS  EQUAL TO =

### Quick Practice

1000 ____ 1,001

12,435 ____ 12,345

One million ____ 1,000,000

=

Both Hands

>

Right Hand

<

Left Hand

What is larger?

0.1 – One Tenth or 0.01 One Hundredth

### Why are decimals different?

>

0.1 ______ 0.0999999

0.09 ______ 0.001

0.84 ______ 0.84000000

0.0555 ______ 0.5

6.7 ______ 7.1

Line up numbers by place value (Decimal Dave)

2) Start at the LEFT and find the place where the digits are different

### Steps for Ordering Decimals

1)

0.890 _________ 0.9

2) Order from Least to Greatest

0.6 0.66 6.7 0.07

<

0.07 0.6 0.66 6.7

3) Order from Greatest to least

0.4 4.4 0.044 4.44

4)

0.2000 ________ 0.2

=

4.44 4.4 0.4 0.044
