Question

which choice shows the best estimate of the product $0.48 \times 591$?
$\frac{1}{2} \times 600$ $1 \times 1,000$
$0 \times 500$ $\frac{1}{4} \times 600$

Explanation:

Step1: Estimate 0.48

0.48 is close to $\frac{1}{2}$ (since $\frac{1}{2} = 0.5$ and 0.48 is near 0.5).

Step2: Estimate 591

591 is close to 600 (as 591 is near 600).

Step3: Identify the best estimate

So the best estimate of $0.48\times591$ is $\frac{1}{2}\times600$.

Answer:

$\frac{1}{2} \times 600$ (the first option)
