 Estimate the products:  
i. 6.1 × 67.39 =

To estimate the product of \(6.1 \times 67.39\), let's round the numbers to easier, nearby values:

- Round 6.1 to 6.
- Round 67.39 to 67.

Now, estimate:

\[
6 \times 67 = 402
\]

So, the estimated product of \(6.1 \times 67.39\) is approximately **402**.
