Answer 3

[AI-generated answer — Explain Bot]

To estimate 329 + 64 using compatible numbers, we can round both numbers to the nearest tens.

The number 329 can be rounded to 330 since it is closer to 330 than it is to 320.

The number 64 can be rounded to 60 since it is closer to 60 than it is to 70.

Now we can add the rounded numbers:

330 + 60 = 390

Therefore, using compatible numbers, we can estimate that 329 + 64 is approximately equal to 390.
