Question

How can you tell before dividing taht the first digit of the quotient 2,874 divided by 3 is in the hundreds place?

Answer 1

When you divide, you're doing the oposite of multiplication. To know that your partical answer is going to be in the hundreds place is you follow the pattern.
2874/3=958
you take the 3 and you divide it by the last two didits of the number given (28) and that'll get you into your hundreds place.
