• >

• =

• ≥

• <

In the first example, what is the correct comparison between 4.735 and 4.74?

• 4.735 ≥ 4.74

• 4.735 < 4.74

• 4.735 > 4.74

When comparing decimals, why is it important to line up the decimals?

• To convert them into fractions

• To ensure the place values are correctly compared

• To make the numbers look neat

• To make it easier to add the numbers

In the second example, how do you handle missing place values in a decimal?

• Ignore the missing values

• Fill in the missing values with zeros

• Convert the decimal to a fraction

• Round the decimal to the nearest whole number

What is the correct comparison between 6.700 and 6.7?

• 6.700 > 6.7

In the third example, which decimal is larger: 0.230 or 0.203?

• 0.230

• 0.203

• They are equal

• Cannot be determined

When ordering decimals from greatest to least, what is the first step?

• Add all the decimals together

• Convert the decimals to fractions

• Line up the decimals

• Round all the decimals to the nearest whole number

Which decimal is the greatest among 0.275, 0.257, 0.225, and 1.0?

• 0.275

• 1.0

• 0.257

• 0.225

What should you do if you find it confusing to compare decimals without lining them up?

• Convert them to fractions

• Ignore the decimals and compare the whole numbers

• Round them to the nearest whole number

• Line up the decimals to compare place values
