11 2/3, I think. 2*3 + 1 = 7 & 7/3*5/1 (where you do straight multiplication) you get 35/3 which simplifies to 11 2/3. Hope this helped, but um what is the weight measurement or is that not mentioned?
Weight of each book = 2 ⅓ = 7/3
Weight of 5 books = 5 × 7/3
= 35/3
Weight of 5 books = 5 × 7/3
= 35/3
