A fact family for 81 and 9 consists of addition and subtraction sentences that relate to those two numbers. Since 81 can be expressed as the product of 9 and another number (9 x 9 = 81), the fact family primarily focuses on these two operations. The only two number sentences are 9 + 9 = 81 and 81 - 9 = 9, reflecting the relationship without introducing additional numbers. Thus, the limited number of sentences is due to the specific values and their mathematical relationships.
