When comparing decimals we start by comparing
their place value.
Example: Compare 4.19 and 4.91
First line up the numbers by their decimals.
Start from the left and compare the columns. Stop
at the first place where the numbers are different.
The Numbers in the tenths place is different.
9 is greater than 1
So 4.91 > 4.19
You can write extra zeros to the right of the decimals
being compared. These extra zeros are place holders
and do not change the value of the decimals.
Example: 1.8076 = 1.80760 = 1.807600
