for each expression, estimate to decide whether the sum is closer to 400 or 500. closer to 400 closer to 500 311 + 198

Answer

Explanation:

Step1: Round each addend

$311 \approx 310$, $198 \approx 200$

Step2: Calculate estimated sum

$310 + 200 = 510$

Step3: Compare to 400 and 500

$|510 - 400| = 110$, $|510 - 500| = 10$

Answer:

Closer to 500
