*) Which number is a reasonable estimate for \( 1,519 \div 49 \) ? \begin{tabular}{|c|c|c|c|}\hline 10 & 30 & 100 & 300 \\ \hline\end{tabular}

To estimate \( 1,519 \div 49 \), it's helpful to round the numbers for easier mental math. You can round 49 to 50, which makes the division simpler. Now, dividing 1,500 by 50 gives you 30. Among the options provided, 30 is the closest reasonable estimate for the division. Also, breaking it down further can help! You might consider that \( 49 \) is nearly \( 50 \), so multiplying \( 50 \times 30 = 1,500 \), which is very close to \( 1,519 \). Therefore, it's reasonable to say that around 30 is the right estimate for the original division problem!
