1624 DIVIDED BY 3 FIND TWO ESTIMATES THAT THE QUOTIENT IS BETWEEN?

Answer 1

Estimates mean you use "gentle easy numbers" those that are good and easy to work with (without a calculator)
What about
1) 1500 divided by 3
or
2) 1600 divided by 2
Those are "gentle" numbers that give you a good range.

Answer 2

but most people should be able to
divide 1624 by 3 mentally to get 541 1/3
