The fact family for the numbers 3, 0, and 0 includes the addition and subtraction equations that can be formed using these numbers. The equations are: (3 + 0 = 3), (0 + 3 = 3), (3 - 0 = 3), and (0 - 0 = 0). Since 0 does not change the value when added or subtracted, it plays a neutral role in this fact family.
The fact family of 0, 0, and 4 would include the addition and subtraction equations: 0 + 0 = 0, 0 + 4 = 4, and the subtraction equation: 4 - 0 = 4.
The fact family of 3 and 9 3+9 9+3 9-3 3-9
1 & 3
write three numbers that makes a fact family
The operation, division, is not symmetric. There is a number, x, such that x*3 = 0. In fact x is also 0. But there is no number, y, such that y*0 = 3.
the fact family is 3 because 3 goes into all of them
The fact family of 0, 0, and 4 would include the addition and subtraction equations: 0 + 0 = 0, 0 + 4 = 4, and the subtraction equation: 4 - 0 = 4.
The fact family of 3 and 9 3+9 9+3 9-3 3-9
A fact family for the number 6742 includes a set of related addition and subtraction equations. The fact family can be represented by the equations: 6742 + 0 = 6742, 0 + 6742 = 6742, and 6742 - 0 = 6742. In this case, since 6742 is a single number, it forms a simple family focused solely on itself. For a more complex fact family, additional related numbers would be needed.

Fact families are 3 numbers that are related, just as the people in a family are related. They make a set of related math facts.
A fact family is when the same 3 numbers are used in addition and subtraction sentences. An example would be 3+4=7, 4+3=7, 7-4=3 and 7-3=4
Yes, the number 12 can be part of more than one fact family. A fact family consists of a set of related addition and subtraction or multiplication and division equations involving the same numbers. For example, the numbers 12, 4, and 3 can form the addition and subtraction fact family (3 + 4 = 7, 7 - 4 = 3, etc.) and also the multiplication and division fact family (3 x 4 = 12, 12 ÷ 4 = 3, etc.). Thus, 12 can belong to multiple fact families based on different combinations of numbers.
