Answer:
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. In this case we use multiplication and division.
Step-by-step explanation:
Multiplication: 9 x 5 is 45
Same as 5 x 9 is 45
Division: 45 ÷5 is 9
Same as 45÷9 is 5
