Question

Without actual calculation, estimate:

$449\times 29$

Answer 1

The estimate $449$ is nearest to a tens $=450$

The estimate $29$ is nearest to a hundred $=30$

$$\begin{gathered} \therefore 449\times 29=450\times 30 \\ =13500 \end{gathered}$$

Hence, the estimate calculation for the given expression is $13,500.$
