1 ) the weight of 56 books
2) the number of books in 4 kg​

Answer 1

Answer:

1) 294 Kg

2) $\frac{16}{21}$ books

Step-by-step explanation:

Solve this question by using the concept of unitary method.

1) The weight of 36 books = 189 kg

The weight of 1 books = $\frac{189}{36}$kg

The weight of 56 books = $\frac{189}{36}$kg × 56 = 294 Kg

2) Numbers of book in 189 Kg = 36

   Numbers of book in 1 kg = $\frac{36}{189}$

   Number of books in 4 kg​ =  $\frac{36}{189}$ × 4 = $\frac{16}{21}$ books
