Asha plans to place vacation photos of her friends on a square bulletin board measuring 72 units by 72 units.

Question

a) Which size of phot can be placed without any spaces or overlapping?

10 X 8
6 X 4
5 x 7

Answer 1

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?

Answer 2

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

Answer 3

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

Answer 4

Right. And 72/4 also comes out even.

Answer 5

Thank you sooo much :)

Answer 6

b? So how many photos of that size can be placed on the bulletin board?

Answer 7

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

Answer 8

Along one side you could place 12 photos and along another side you could place 18 photos.

Multiply:

12 * 18 = ?
