Answers

To estimate \( 281 \times 2.16 \), we can round the numbers to make the calculation easier.

- Round \( 281 \) to \( 280 \)
- Round \( 2.16 \) to \( 2.2 \)

Now we can calculate:

\[
280 \times 2.2
\]

To make it easier, we can break it down further:

\[
280 \times 2.2 = 280 \times (2 + 0.2) = 280 \times 2 + 280 \times 0.2
\]

Calculating each part:

\[
280 \times 2 = 560
\]
\[
280 \times 0.2 = 56
\]

Now add them together:

\[
560 + 56 = 616
\]

So, an estimate for \( 281 \times 2.16 \) is approximately \( 616 \).
