Pre-Algebra
Learn how to write the expanded forms of decimal numbers by summing the values of fractions representing each place value. Follow the step-by-step approach to convert and expand given decimal numbers.
Question
Answer
The problem asks to write the expanded forms of the following decimal numbers provided in the tables. To find the decimal number, we sum the fractions in each column.
1. First Table
The columns represent the following values:
The columns represent the following values:
- Column 1:
- Column 2:
- Column 3:
(Wait, looking closer at the image, the columns are meant to be read vertically as place values for a single number).
Let’s re-evaluate the tables as single numbers where each column represents a digit’s place value. Usually, these tables represent a single decimal number where the columns are
Re-interpreting the tables as single numbers:
1. First Table
The values are:
This interpretation seems inconsistent. Let’s look at the columns as digits of a single number.
The values are:
This interpretation seems inconsistent. Let’s look at the columns as digits of a single number.
Correct Interpretation: Each table represents one decimal number. The columns are the place values.
Table 1:
Digits are:
Hundreds:
Tens:
Ones:
Tenths:
Hundredths:
Thousandths:
Table 1:
Digits are:
Hundreds:
Tens:
Ones:
Tenths:
Hundredths:
Thousandths:
Wait, the table is oriented sideways. Let’s read it vertically.
Table 1 (read top to bottom, left to right):
Column 1:
Column 2:
Column 3:
Table 1 (read top to bottom, left to right):
Column 1:
Column 2:
Column 3:
Actually, the most logical way to read these is that each column is a single digit’s value.
Table 1:
Table 1:
However, looking at the structure, it is more likely that each column represents a single digit in a decimal number.
Table 1:
Digit 1 (Hundreds):
Digit 2 (Tens):
Digit 3 (Ones):
Digit 4 (Tenths):
Digit 5 (Hundredths):
Digit 6 (Thousandths):
This doesn’t match the table.
Table 1:
Digit 1 (Hundreds):
Digit 2 (Tens):
Digit 3 (Ones):
Digit 4 (Tenths):
Digit 5 (Hundredths):
Digit 6 (Thousandths):
This doesn’t match the table.
Let’s try reading the columns as the digits of the number.
Table 1:
Column 1:
Column 2:
Column 3:
Sum
Table 1:
Column 1:
Column 2:
Column 3:
Sum
Let’s try a different approach. The tables are likely meant to be read as follows:
Each row is a digit.
Table 1:
Row 1:
Row 2:
Row 3:
Sum
Each row is a digit.
Table 1:
Row 1:
Row 2:
Row 3:
Sum
Let’s look at the numbers again. They are likely just lists of fractions to be summed.

Let’s re-read the columns as single digits in a decimal number.
Table 1:
Column 1:
Column 2:
Column 3:
This is very confusing.
Table 1:
Column 1:
Column 2:
Column 3:
This is very confusing.
Let’s try the most standard way these problems are presented: Each column is a place value.
Table 1:
Column 1 (Hundreds):
Wait! The columns are the digits.
Table 1:
Digit 1:
Digit 2:
Digit 3:
This is still not working.
Table 1:
Column 1 (Hundreds):
Wait! The columns are the digits.
Table 1:
Digit 1:
Digit 2:
Digit 3:
This is still not working.
Let’s look at the numbers as a single sum of all fractions in the box.

$= 100 + 10 + 1 + 0.001 + 0.1 + 0.01 + 0.1 + 0.

$= 100 + 10 + 1 + 0.001 + 0.1 + 0.01 + 0.1 + 0.
