Responses

917
9 and 1 seventh

937
9 and 3 sevenths

647
6 and 4 sevenths

637

Answer 1

To estimate \( 3 \times \pi \), we can use the fact that \( \pi \) is approximately \( 3.14 \).

Calculating \( 3 \times \pi \):
\[
3 \times \pi \approx 3 \times 3.14 = 9.42
\]

Now we can compare this with the given options:

1. **917**
2. **9 and 1 seventh** (which is approximately 9.14)
3. **937**
4. **9 and 3 sevenths** (which is approximately 9.43)
5. **647**
6. **6 and 4 sevenths** (which is approximately 6.57)
7. **637**

The best estimate for \( 3 \times \pi \approx 9.42 \) is **9 and 3 sevenths** (since it is the closest approximation).

So the correct response is:
**9 and 3 sevenths**.
