GPT-4o mini
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 \( 616 \).
- 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 \( 616 \).
