3x9=3x3x3=27
Not sure what you mean by break apart.
One way to do it in your head if you need to and don't just know it is 27 is to say 3x10=30 which is easy because adding tens is easy for most people.
Now 3x9 is one less 3 then 3x10. That is to say, think of 3x9 as 9 threes, and 10x3 as 10 threes.
So 30-3 is 27
breaking the array 3x9=27 3x3=9 3x3=9 3x3=9 9+9+9=27 one more way of doing it is 3x3=9 and 3x6 =18 , 9+18 =27
The fact that 3 x 9 = 27

Yes, 27 is a multiple of 3. 3x9=27 (3,6,9,12,15,18,21,24,27)
because their the same number just switched in place

The whole numbers that multiply to make 27 are: 1x27, and 3x9.
3x9 ones = 27
The fact that 3 x 9 = 27
27
yes
3x9, 3x3x3, or 1x27
Mutltiplying fractions? That's no problem! Top times top and bottom times bottom.For example: 3/4 x 9/10 = ?To solve this problem you multiply the Numerators: 3x9=27Then you multiply the Denominators: 4x10=40Which gets you your product: 27/40
