Comparing and Ordering Decimals

The video tutorial covers how to compare and order decimals, including examples of comparing decimals with different numbers of digits and negative decimals. It explains the importance of aligning decimal points and adding zeros for comparison. The tutorial also addresses comparing fractions and decimals by converting fractions into decimals. Finally, it discusses ordering decimals from least to greatest and greatest to least, emphasizing the need to align decimal points and fill in blanks with zeros.

What is the first step when comparing two decimals?

• Add zeros to the shorter number

• Align the decimal points

• Convert them to fractions

• Compare the digits from left to right

When comparing 4.235 and 4.2359, what should you do to make the comparison easier?

• Add a zero to 4.235

• Convert them to fractions
