Why Estimate Before Dividing?

1 pts

volume_mute

What is the main reason to estimate a quotient before performing exact long division?

To get an exact answer without doing the full division.

To get a rough idea of the size of the answer and to check for errors.

To determine which divisibility rule applies.

To find the remainder without any calculation.
