Section A: Practice Problems Decimals with Tenths and Hundredths
Section Summary
Details
In this section, we learned to express tenths and hundredths as decimals, locate them on a number line, and compare them.
We learned that
The table shows some more examples of tenths and hundredths in their decimal notation.
Because
and are equivalent, the decimals 0.5 and 0.50 are also equivalent. Likewise,
and are equivalent, so 1.7 and 1.70 are also equivalent.

Just like fractions, decimals can be located on a number line. Doing so can help us compare them.
For instance, 0.24 is equivalent to
Problem 1 (PreUnit)
Round each number to the nearest 10 and to the nearest 100.
63
350
485
Problem 2 (PreUnit)
A number
Round
to the nearest multiple of 100. Explain your reasoning. Can you tell what
is if rounded to the nearest multiple of 10? Explain your reasoning.
Problem 3 (PreUnit)
Find the value of each expression. Show your reasoning.
Problem 4 (PreUnit)
Here are three numbers: 265, 652, and 526. For each question, explain your reasoning.
Does the digit 6 have a greater value in 265 or 652?
Does the digit 5 have a greater value in 265 or 652?
In which number does the digit 2 have the greatest value? In which one does it have the least value?
Problem 5 (Lesson 1)
Each large square represents 1.
Write a fraction and a decimal that represent the shaded part of the large square.

Problem 7 (Lesson 3)
Locate and label 0.6 and 0.35 on the number line.
Compare 0.6 and 0.35 using < or >.
Problem 8 (Lesson 4)
Order the numbers from least to greatest:
Problem 9 (Lesson 5)
Order the numbers from least to greatest:
Problem 10 (Exploration)

Problem 11 (Exploration)
In a recent lesson, you learned about the lengths of the jumps made by Carl Lewis and other athletes.
Create and label a number line to show the distances of all ten jumps made by the athletes.
