what is the fact family for 4,6 and 9

36

If you are doing it for addition/subtraction it could be:

6 + ? = 9
? + 6 = 9
9 - 6 = ?
9 - ? = 6

4 + ? = 9
? + 4 = 9
9 - 4 = ?
9 - ? = 4

For multiplication/division, it could be:

4 * 9 = 36
9 * 4 = 36
36/4 = 9
36/9 = 4

I hope this helps.
6 * 6 = 36
36/6 = 6
