Answer:
A. Yes
B. No
Step-by-step explanation:
We have that,
A. The dimensions of the each of the paper is 8.5 × 11.
Since, the papers have equal dimensions, the weight of every paper will be same and it will be easy to find the number of papers using direct proportion.
Thus, the weight of the paper and the number of papers is proportional.
B. It is given that the weight of each book is different.
Since, all the books have different weights, it is not easy to find the number of papers using direct proportion.
Hence, the weight of the books and the number of books is not proportional.
