Answer 2

Step-by-step explanation:

a)Weight of 72 books = 9 kg

total books at weight of 1 kg = 72÷9 = 8

8 books are at 1 kg then,

weight of 80 books = books in 1 kg is 8 books

weight of 80 books = 80÷8 = 10 kg

hence , weight of 80 books is 10 kg

b)total books at weight 1 kg = 8 books

total books at weight 6 kg = 8 × 6 = 48 books

hence , 48 books are at weight of 6 kg .
