Question

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

Answer 1

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
