### Question 1
# Explanation:
## Step1: Identify digit positions
The number is $5,192,478,600$. From right, positions: ones, tens, hundreds, thousands, ten - thousands, hundred - thousands, millions, ten - millions, hundred - millions, billions.
Digit 1: Count positions. The 1 is at the 9th position from right (billions? Wait, no: Let's write the number with commas: 5 (billion), 1 (hundred - million), 9 (ten - million), 2 (million), 4 (hundred - thousand), 7 (ten - thousand), 8 (thousand), 6 (hundred), 0 (ten), 0 (one). Wait, no, commas in US system: groups of three. So $5,192,478,600$ is 5 (billion), 192 (million), 478 (thousand), 600 (ones). Wait, no, each group: first group (rightmost) is ones (3 digits), then thousands (next 3), then millions (next 3), then billions (next 3). So positions:
- Billions: 5 (1st digit from left)
- Hundred - millions: 1 (2nd digit from left)
- Ten - millions: 9 (3rd)
- Millions: 2 (4th)
- Hundred - thousands: 4 (5th)
- Ten - thousands: 7 (6th)
- Thousands: 8 (7th)
- Hundreds: 6 (8th)
- Tens: 0 (9th)
- Ones: 0 (10th)
So digit 1 is in the hundred - millions place. Wait, but maybe the original thought was wrong. Wait, let's count the place values properly. The number is $5,192,478,600$. Let's write it as:

$5\times10^{9}+1\times10^{8}+9\times10^{7}+2\times10^{6}+4\times10^{5}+7\times10^{4}+8\times10^{3}+6\times10^{2}+0\times10^{1}+0\times10^{0}$

So the digit 1 is multiplied by $10^{8}$, which is the hundred - millions place. But maybe the intended answer was 100,000,000 (hundred - million) place. Wait, the student wrote 100,000,000. Let's confirm:

The number: 5 (billion), 1 (hundred - million), 9 (ten - million), 2 (million), 4 (hundred - thousand), 7 (ten - thousand), 8 (thousand), 6 (hundred), 0 (ten), 0 (one). So digit 1 is in the hundred - millions place, which has a value of $1\times10^{8}=100,000,000$. So the place is hundred - millions place (or 100,000,000 place).

## Step2: Conclusion
The digit 1 is in the hundred - millions place (or $10^{8}$ place), and the value of that place is 100,000,000. So the answer for question 1 is 100,000,000 (hundred - millions place).

# Answer: 100,000,000 (hundred - millions place)

### Question 2
# Explanation:
## Step1: Identify digit 4's position
In $5,192,478,600$, digit 4 is at the hundred - thousands place.
## Step2: Calculate value
The place value of hundred - thousands is $10^{5}$. So the value of digit 4 is $4\times10^{5}=400,000$.

# Answer: 400,000

### Question 3
# Explanation:
## Step1: Identify digit 5's position
In $5,192,478,600$, digit 5 is at the billions place.
## Step2: Determine the value
The place value of billions is $10^{9}$, so 5 in the billions place stands for 5 billion.

# Answer: 5 billion (the option to circle is "5 billion")

### Question 4
# Explanation:
## Step1: Identify the thousands place
In the number $5,192,478,600$, the thousands place is the 4th digit from the right in the thousands group. The number is grouped as $5,192,478,600$ (billions, millions, thousands, ones). The thousands group is 478,600? Wait, no, the thousands group is the three digits before the last three (ones). Wait, the number is $5,192,478,600$. Let's split into groups:

- Billions: 5
- Millions: 192
- Thousands: 478
- Ones: 600

Wait, no, the correct grouping is: from right, first three digits: 600 (ones), next three: 478 (thousands), next three: 192 (millions), next three: 5 (billions). Wait, no, the number of digits: $5,192,478,600$ has 10 digits. So positions (from right, starting at 0):

- Position 0: 0 (ones)
- Position 1: 0 (tens)
- Position 2: 6 (hundreds)
- Position 3: 8 (thousands)
- Position 4: 7 (ten - thousands)
- Position 5: 4 (hundred - thousands)
- Position 6: 2 (millions)
- Position 7: 9 (ten - millions)
- Position 8: 1 (hundred - millions)
- Position 9: 5 (billions)

So the thousands place is position 3, and the digit there is 8.

# Answer: 8

### Question 5
# Explanation:
## Step1: Identify digit 6's position
In $5,192,478,600$, digit 6 is at the hundreds place.
## Step2: Calculate value
The place value of hundreds is $10^{2}$. So the value of digit 6 is $6\times10^{2}=600$.

# Answer: 600

### Question 6
# Explanation:
## Step1: Break down the number name
"Four hundred twenty - three thousand, twenty - five"
- Four hundred twenty - three thousand: $423\times1000 = 423000$
- Twenty - five: $25$
## Step2: Add them together
$423000 + 25=423025$

# Answer: 423,025

### Question 7
# Explanation:
## Step1: Add the numbers
We have $800,000+4,000 + 60+2$
- First, $800,000+4,000=804,000$
- Then, $804,000+60 = 804,060$
- Then, $804,060+2=804,062$

# Answer: 804,062

### Question 8
# Explanation:
## Step1: Add the numbers
We have $100,000+900 + 20+3$
- First, $100,000+900 = 100,900$
- Then, $100,900+20=100,920$
- Then, $100,920+3 = 100,923$ (Wait, the student wrote 100,973, which is wrong. Let's correct it.)

# Answer: 100,923

### Question 9
# Explanation:
## Step1: Expanded Form (EF)
The number is $702,006$. We break it down by place values:
- $7\times100,000+0\times10,000 + 2\times1,000+0\times100+0\times10+6\times1$
- Which is $700,000+2,000 + 6$
## Step2: Word Form (WF)
We read the number: "Seven hundred two thousand six" (or "Seven hundred two thousand and six")

# Answer:
EF: $700,000 + 2,000+6$
WF: Seven hundred two thousand six

### Question 10
# Explanation:
## Step1: Expanded Form (EF)
The number is $7,065.94$. We break it down by place values (including decimals):
- $7\times1,000+0\times100+6\times10+5\times1+9\times0.1+4\times0.01$
- Which is $7,000+60 + 5+0.9+0.04$
## Step2: Word Form (WF)
We read the number: "Seven thousand sixty - five and ninety - four hundredths"

# Answer:
EF: $7,000+60 + 5+0.9+0.04$
WF: Seven thousand sixty - five and ninety - four hundredths
