Answer:

Answer 1

Let's go through each part of your request step by step:

1. **Placing the Decimal Point:**
The product that does not show a decimal point can be 631070. We have to place the decimal point in such a way that it yields a reasonable value. To express it with decimals:

- Place the decimal point between 0 and 7: 63107.0 (which is 63107)
- Place the decimal point between 7 and 2: 6310.7
- Place the decimal point between 2 and 3: 631.07
- Place the decimal point between 3 and 8: 63.107

**Answer:** The equivalent decimal forms are 63107, 6310.7, 631.07, and 63.107.

2. **Finding the Product:**
For the numbers represented as 631070, if we consider the original product as 631070, it seems you want to know which representation is correct:

- 6,310.7 is a reasonable representation if we treat it as 63107.0 after adding the decimal.
- 63,107 is also valid.
- 631,070 is not implied here since it suggests a larger value.
- 6,310,700 is definitely larger and incorrect.

**Answer:** The valid representations from this context are 6,310.7 and 63,107.

3. **Juanita's Earnings:**
Juanita earns $8.75 per hour and works 23 hours. To calculate her earnings:

\[
Earnings = Hourly Rate \times Hours Worked = 8.75 \times 23
\]
\[
Earnings = 201.25
\]

**Answer:** $201.25

4. **Estimating the Product of 228 and 11.4:**
Rounding to the nearest ten:

- 228 rounds to 230.
- 11.4 rounds to 10.

Now, we find the product:

\[
Estimated Product = 230 \times 10 = 2300
\]

To find the exact product:

\[
Actual Product = 228 \times 11.4 = 2599.2
\]

**Answer:** Estimated product is 2300, and the actual product is 2599.2.
