Representing Decimals in Expanded Form

Numbers can be written in standard notation or expanded form. When numbers are written in expanded form, the value of each digit is clearly shown. The number 3.924 is written in standard notation. The examples below show 3.924 using different versions of expanded form.

  • 3 + 0.9 + 0.02 + 0.004
  • 3 ones + 9 tenths + 2 hundredths + 4 thousandths
  • (3 ∗ 1) + (9 ∗ 0.1) + (2 ∗ 0.01) + (4 ∗ 0.001)
  • (3 ∗ 1) + (9 ∗ \(\frac{1}{10}\) ) + (2 ∗ \(\frac{1}{100}\) ) + (4 ∗ \(\frac{1}{1000}\))

In Problems 1–4, represent each decimal using one version of expanded form.

4.203 = 4 ones + 2 tenths + 0 hundredths + 3 thousandths.

Question 3.
0.068
Answer:
0.068 = (0 ∗ 0) + (0 ∗ 0.1) + (6 ∗ 0.01) + (8 ∗ 0.001),

Explanation:
The expanded form of 0.068 is
0.068 = (0 ∗ 0) + (0 ∗ 0.1) + (6 ∗ 0.01) + (8 ∗ 0.001).

Question 4.
8.415
Answer:
8.415 = (8 ∗ 1) + (4 ∗ \(\frac{1}{10}\) ) +
(1 ∗ \(\frac{1}{100}\) ) + (5 ∗ \(\frac{1}{1000}\)),

Explanation:
The expanded form of 8.415 is

Question 9.
There 30 colored circles on a rug. \(\frac{1}{5}\)
of the circles are red. How many red circles are on the rug?
____6_____ red circles
Answer:
6 red circles are on the rug,

Explanation:
Given there are 30 colored circles on a rug and
\(\frac{1}{5}\) of the circles are red so
number of red circles are 30 * \(\frac{1}{5}\) = 6,
(5 X 6 = 30), So there are 6 red circles are on the rug.

Question 10.

Answer:
8 students chose soccer,

Explanation:
Given Jerome did a survey to find out his classmates’ favorite sports.
He found that \(\frac{1}{3}\) of the 24 students in
his class chose soccer as their favorite sport.
So number of students chose soccer are
24 * \(\frac{1}{3}\) = 8, (8 X 3 = 24),
So there are 8 students who chose soccer.

Everyday Math Grade 5 Home Link 4.4 Answer Key 2
Answer:
Everyday Math Grade 5 Answers Unit 4 Decimal Concepts; Coordinate Grids-7

Explanation:
Compared Player 1 – Darryl and Player 2- Charity
with their decimals for each round as
Round 1:
0.378 is less than 0.860 so 0.378 < 0.860,
Round 2:
0.9 is greater than 0.59 so 0.9 > 0.59,
Round 3:
0.804 is less than 0.92 so 0.804 < 0.92,
Round 4:
0.547 is less than 0.6 so 0.547 < 0.6,
Round 5:
0.72 is greater than 0.098 so 0.72 > 0.098.

Question 2.
Who won the most rounds?
Answer:
Charity won the most rounds,

Explanation:
If we see out of five rounds,
3 rounds Round 1, 3, 4 player 2 is having most,

Question 5.
\(\frac{3}{8}\) + ______ < 1
Answer:
\(\frac{1}{4}\),

Explanation:
Given \(\frac{3}{8}\) + ______ < 1,
we take missing number as \(\frac{1}{4}\),
so \(\frac{3}{8}\) + \(\frac{1}{4}\) =
\(\frac{5}{8}\) whose value is less than 1,
if we take \(\frac{2}{3}\) the value is greater than 1,
if we take \(\frac{7}{8}\) the value is equal to 1 and
if we take \(\frac{3}{4}\) the value is greater than 1,
therefore the correct value would be \(\frac{1}{4}\).

Question 6.
_______ – \(\frac{1}{8}\) < 1
Answer:
\(\frac{7}{8}\)

Explanation:
Given _______ – \(\frac{1}{8}\) < 1
we take missing number as \(\frac{7}{8}\),
so \(\frac{7}{8}\) – \(\frac{1}{8}\) =
\(\frac{6}{8}\) whose value is less than 1,
even if we take other 2 values are also coming true.

Question 7. _____ + ______ > 1
Answer:
\(\frac{2}{3}\) and \(\frac{3}{4}\),

Explanation:
Given _____ + ______ > 1, we have now
\(\frac{2}{3}\) and \(\frac{3}{4}\),
So \(\frac{2}{3}\) + \(\frac{3}{4}\) =
\(\frac{17}{12}\) we get value more than 1,
therefore we took \(\frac{2}{3}\) and \(\frac{3}{4}\).

Everyday Mathematics Grade 5 Home Link 4.9 Answers 1

Everyday Math Grade 5 Answers Unit 4 Decimal Concepts; Coordinate Grids-17
Explanation:
Given Clay reads the same amount of a book each day.
The table showed how many chapters of the
book he has read at the end of each day.
Wrote the data from the table as ordered pairs as
(1,3), (2,6), (3,9), (4,12), (5,15) and
Plotted the points on the grid and
connected them in a line as shown above.

Question 1.
Between which two days did Clay finish reading Chapter 5 in the book?
Between days _____1_____ and ____2____
Answer:
Clay finished reading Chapter 5 in the book
between days 1 and 2,

Explanation:
By seeing the table data it is clear that Chapter 5
comes in between Chapter 3 and Chapter 5, So
Clay finished reading Chapter 5 in the book
between days 1 and 2.

Question 2.
About how many chapters had Clay read half-way
through the fourth day (Day 3\(\frac{1}{2}\))?
Answer:
Number of chapters did Clay read half-way through
the fourth day (Day 3\(\frac{1}{2}\)) is 10 or 11,

Explanation:
By seeing the table data it is clear that
number of chapters Clay read half-way through
the fourth day (Day 3\(\frac{1}{2}\)) is in
between 9 and 12 so 10 or 11.

Question 3.
If the book has 17 chapters, on what day would
Clay complete the book?
Answer:
Some time on the sixth day,

Explanation:
By seeing the table data it is clear that
If the book has 17 chapters, the day Clay would
complete the book would be some time on the sixth day.

Question 4.
Explain how you found your answer to Problem 3.
Answer:
By calculating using the given table data,

Explanation:
By seeing the table data it is clear that from
End of Day 1 completed chapters are 3,
Day 2 it is 3 + 3 = 6, Day 3 it is 6 + 3 = 9,
Day 4 it is 9 + 3 = 12 and Day 5 it is 12 +3 = 15,
means everyday it is 3 chapters,
So If the book has 17 chapters, the day Clay would
complete the book would be some time on the sixth day.

Answer:
3.971 to the nearsest hundreth is 3.97,

Explanation:
Given 3.971, We know the hundredths place is
the second digit to the right of the decimal point.
So the nearest hundreth to 3.971 is 3.97.

Question 7.
84.099 ____84.10____
Answer:
84.099 to the nearsest hundreth is 84.10,

Explanation:
Given 84.099, We know the hundredths place is
the second digit to the right of the decimal point.
So the nearest hundreth to 84.099 is 84.10.

Question 8.
