Aseem and Chadda have 316 photos to put in 2 scrapbooks. They agree to put the same number of photos in each book. But they disagree about how many photos that is.
Aseem: We can put more than 100 photos in each book.
Chadda: We don’t have enough photos to put 100 in each book.
Who is right? Show and explain your thinking.
Answer:
Therefore, the number of photos in each book are 158.
Aseem is right because more than 100 photos can be put in each book.
