Explanation:

Step1: Determine the fact family

A fact family is a set of related addition and subtraction facts, or multiplication and division facts, made from the same numbers.
For the numbers \(15\), \(5\), and \(3\):

• Multiplication: \(3\times5 = 15\)
• Multiplication: \(5\times3=15\)
• Division: \(15\div3 = 5\)
• Division: \(15\div5=3\)

Answer:

1. \(3\times5 = 15\)
2. \(5\times3 = 15\)
3. \(15\div3 = 5\)
4. \(15\div5 = 3\)
