Math 6A (Periods 1 & 2)

Comparing Decimals 3-4



In order to compare decimals, we compare the digits in the place farthest to the left where the decimals have different digits.

Compare the following:


1. 0.64 and 0.68 since 4 < 8 then 0.64 < 0.68.


2. 2.58 and 2.62 since 5 < 6 then 2.58 < 2.62 .


3. 0.83 and 0.833

To make it easier to compare, first express 0.83 to the same number of decimal places as 0.833

0.83 = 0.830 Then compare


0.830 and 0.833 since 0 <3 br="br">
Then 0.830 < 0.833.


Write in order from least to greatest


4.164, 4.16, 4.163, 4.1



First, express each number to the same number of decimal places

Then compare. 4.164, 4.160, 4.163, 4.100


The order of the numbers from least to greatest is


4.1, 4.16, 4.163, 4.164
4.1< 4.16 < 4.163 < 4.164
