To estimate \( 14.2 \div 3.2 \), we can round the numbers to make the division easier.
- Round \( 14.2 \) to \( 14 \) (or \( 15 \), but we'll use \( 14 \) for easier calculation).
- Round \( 3.2 \) to \( 3 \).
Now, we can perform the division:
\[ 14 \div 3 \approx 4.67 \]
Looking at the options provided (4, 5, 6), the best estimate for \( 14.2 \div 3.2 \) is:
