Question

Choose the best estimate for the difference $611-298.$

• A. $500-300$
• B. $600-200$
• C. $700-200$
• D. $600-300$

Answer 1

The correct option is D $600-300$

Rounding off 611 and 298 to the nearest hundreds, we get 600 and 300.

611 $\to$ 600
298 $\to$ 300

$\therefore$ 611 - 298 $\to$ 600 - 300

Thus, the best way to estimate the difference $611-298$ is $600-300.$
