sam has 12 black-and-white photos and 18 color photos. He wants to put the photos in equal rows so each row has either black-and-white photos only or color photos only. In how many rows can Sam arrange the photos
depends on how big of rows and columns (side to side or up and down) 3 by 4 for black and white and 3 by 6 for color just reverse the numbers so it'll be in stead 4 by 3 and 6 by 3 hope this makes sense
