Question

the weight of two books together is 13/4kg if the weight of one book is 7/5kg find the weight of the other book ​

Answer 1

Answer:

Weight of the other book is 37/20 kg

Answer 2

Answer:

37/20 kg or 1.85 kg

Step-by-step explanation:

Let weight of the book be x.

Now, acc. to ques, combined weights of both books = 13/4 kg

One book's weight = 7/5 kg (given)

=> (7/5 + x) kg = 13/4 kg

∴ x = (13/4 - 7/5) kg

=> (65 - 28)/20 => 37/20 kg or 1.85 kg

Thus, the weight of the other book is 37/20 kg or 1.85 kg.
