## 🔑 Key Concept: Division Fact Families
Division is the inverse of multiplication.
If:
>
Dividend ÷ Divisor = Quotient
Then:
>
Divisor × Quotient = Dividend
So, to find a missing divisor:
>
Divisor = Dividend ÷ Quotient
To find a missing dividend:
>
Dividend = Divisor × Quotient
We’ll use this logic for every problem.
