What multiplication fact can be found by using the arrays for 2x9 and 5x9?

• Math - Guido, Monday, February 11, 2008 at 5:18pm

  Multiplication facts:
  
  2 x 9 means two rows times 9 columns.
  
  Facts:
  
  2 x 9 = 18
  
  18/2 = 9
  
  18/9 = 2
  
  9 x 2 = 18
  
  Do the same with the other other numbers.
  
  Also, note that 2 and 9 are factors of 18 and 18 itself is the product of 2 and 9.

  The answer is "7x9".
  
  Because the array of 2x9:
  
  •••••••••
  •••••••••
  
  And the array of 5x9:
  
  •••••••••
  •••••••••
  •••••••••
  •••••••••
  •••••••••
  
  When added together or in the verbiage of the question "can be found by using the arrays".
  
  You have 7 rows of 9. Or "7x9"
