Answer :

ABIDEMIOKINGO

Answer:

6 shelves

Step-by-step explanation:

Let the number of shelves needed be s

If the total number of books to be displayed is 390books

If Each shelf can hold 65 books, then;

1 shelf = 65books

To know the  total shelf needed;

s = 390 books

Divide both expressions

1/s = 65/390

65s = 390

Divide through by 65

65s/65 = 390/65

s = 390/65

s = 6

Hence 6 shelves will be needed
