Answer 1

Ответ:

75 копеек

Пошаговое объяснение:

Если переплет равен х, а книга дороже на 64 рубля, то стоимость книги равняется х+64

х+(х + 64) = 65,5

х+х+64 = 65,5

2х = 65,5-64

х = 1,5/2=0,75 рубля или же 75 копеек

Answer 2

To find the cost of the bookbinding, we can subtract the cost of the book from the total cost, which is 65 rubles and 50 kopeks. The book is more expensive than the binding by 64 rubles.

Let's calculate the cost of the bookbinding:

Total cost of the book and binding: 65 rubles and 50 kopeks Cost of the book: 64 rubles

To find the cost of the binding, we subtract the cost of the book from the total cost:

Cost of the binding = Total cost - Cost of the book

Cost of the binding = 65 rubles and 50 kopeks - 64 rubles

To subtract the rubles, we need to convert the kopeks to rubles. Since 100 kopeks make 1 ruble, we divide the kopeks by 100:

Cost of the binding = 1 ruble and 50 kopeks

Therefore, the cost of the binding is 1 ruble and 50 kopeks.
