Understanding Inverse Operations in Multiplication and Division

What is a number family in the context of multiplication?

• A group of numbers that add up to a specific sum

• A set of numbers that can be rearranged to form different multiplication sentences

• A series of numbers that are all prime

• A collection of numbers that are all even

How are multiplication and division related?
