Question

Neha wants to estimate the product of 293 and 724. What would be the BEST way to do so?

• A. $200\times 700$
• B. $300\times 700$
• C. $300\times 750$
• D. $300\times 800$

Answer 1

The correct option is B

$300\times 700$

Rounding off to the nearest hundreds will be the best way to estimate.

293 rounded off to nearest hundreds = 300 and 724 rounded off to nearest hundreds = 700.

Hence, $300\times 700$ is the best option.
