Question

round 1: instead of finding the exact product, choose a number that is close to the product. which number is a reasonable estimate for $5 \times 79$? 400 $5 \times 79$ is about 400. which number is a reasonable estimate for $33 \times 44$? 20,000 12,000 8,000 1,200

Explanation:

Step1: Round factors to tens

Round $33$ to $30$, round $44$ to $40$.

Step2: Calculate estimated product

$30 \times 40 = 1200$

Step3: Compare to options

The result matches one of the given options.

Answer:

1,200
$33 \times 44$ is about 1,200.
