Let’s add the estimated numbers.

800 is a good estimate for the sum of 435 and 368.

700 is not at all a good estimate for the sum of 435 and 368.

Explanation:

435 + 368 = 803

Round off each of the no.s

435 ≈ 400 (nearest hundreds)

368 ≈ 400 (nearest hundreds)

So,

400+400 = 800

Also, 803 ≈ 800 and not 700

So,

700 is not at all a good estimate for the sum of 435 and 368.
