  Hmm -- If she used 10 x 8 photos, she'd have 2 units of spaces. 72 / 10 = 7 a remainder of 2 Which of the other two answers will work?

  72 / 6 = ? 72 / 4 = ? 72 / 5 = ? 72 / 7 = ?

  Would it be 6 x 4? because 72/6 = 12

  Right. And 72/4 also comes out even.

  So would 30 photos be able to fit on the square bulletin board measuring 72 x 72

  Along one side you could place 12 photos and along another side you could place 18 photos. Multiply: 12 * 18 = ?

  ohh... 216 photos can be placed on the bulletin board.
