Comparing and Ordering Decimals• To compare decimals you look at the biggest(furthest left)

place value and compare digits going from left to right, just like you read a book.

• Least to greatest means to go from the smallest number to the biggest number.

• Greatest to least means to go from the biggest number to the smallest number.

• Fastest to slowest means to go from least to greatest. Don’t you want to have the smallest time to win a race????

• Slowest to fastest means to go from greatest to least. You don’t want to have the slowest time in a race, do you?

Adding Decimals

• To add decimals you have to line up your decimal point.

• Ex: 1.2 + 12.3= 1.4 + 2.35=1.2 1.40

+12.3 +2.35 13.5 3.75• You add zero’s to the end of your decimal to

make it easier to add, when needed.

Subtracting Decimals

• To subtract decimals you have to line up the decimal point. Then you subtract just like you would as if there were not a decimal.

Ex: 125.23 - 22.11 =125.23 22.11103.12

• You can add zeros as needed just like when you add decimals.
