∙ 2012-01-18 20:54:20The fact family of 3 and 9 3+9 9+3 9-3 3-9
the fact family is 3 because 3 goes into all of them
3 + 9 = 12 9 + 3 = 12 12 - 9 = 3 12 - 3 = 9
The fact family for 81 has more than 2 factors: 1, 3, 9 are factors: and that is more than two!
so you say that 3*3 equals 9 but the multiplication fact for it is 9 divide by 9 which would equal 1
7+2=9
What number sentence completes t he fact family 45/9 9x5 4x9
9 x 5 = 45
write three numbers that makes a fact family
The answer is 27. In fact, all you have to do to get that is multiply 9 by 3.
3+6=9
4x9=36 9 x 4= 36 36 * 4 = 9 36 * 9= 4
