Texas Go Math Grade 4 Lesson 2.6 Answer Key Compare Decimals
Essential Question
How can you compare decimals?
Answer:
The rules for comparing decimal numbers are as follows:
a. Compare the whole number part first (i.e., compare the digits in front of the decimal). If they are different, then compare the numbers as you would for any whole number.
b. Compare the tenth place.
c. Compare the hundredth place.
Example:

The city park covers 0.64 square miles. About 0.18 of the park is covered by water, and about 0.2 of the park is covered by paved walkways. Is more of the park covered by water or paved walkways?
• Cross out unnecessary information.
• Circle numbers you will use.
• What do you need to find?
One Way Use a model.
Answer:
We know that,
The equivalent of 0.2 is: 0.20
Now,
Compare 0.18 and 0.20
So,
From the rules of comparing decimals,
18 < 20
Hence, from the above,
We can conclude that
The representation of the model with the comparison of the given decimal numbers is:
Other Ways
A. Use a number line.
Locate 0.18 and 0.2 on a number line.
Think: 2 tenths is equivalent to 20 hundredths.
Now,
From the above Number line,
We can observe that
0.18 is closer to 0
So,
0.18 < 0.2.
B. Compare equal-size parts.
- 0.18 is hundredths.
- 0.2 is 2 tenths, which is equivalent to 20 hundredths.
We know that,
18 hundredths < 20 hundredths
So 0.18 < 0.2.
Hence, from the above,
We can conclude that
More of the park is covered by “Paved Walkways”

Can you compare 0.39 and 0.42 by comparing only the tenths? Explain.
Answer:
The given decimal numbers are: 0.39 and 0.42
Now,
We know that,
In the comparison of decimals,
If the whole numbers before the decimal point are the same, then compare the tenths of the decimal numbers
