How can i think of dividing by 11 or 12 as an unknown factor problem?

To think of dividing by 11 or 12 as an unknown factor problem, you can reframe the division as finding a missing factor in a multiplication equation. For example, if you have ( x \div 11 = y ), you can express this as ( y \times 11 = x ), where ( y ) is the unknown factor. Similarly, for division by 12, you would write ( x \div 12 = y ) as ( y \times 12 = x ). This approach allows you to solve for the unknown by manipulating the multiplication equation instead of focusing solely on division.
