Question

You borrow bookcases to display 943 books. You plan to put 22 books on each shelf. There are 5 shelves. How many bookcases do you need

Answer 1

Answer:

9 bookcases.

Step-by-step explanation:

Total number of books = 943

Total number of books placed in one shelf = 22

Total number of shelves in one bookcase = 5

Total number of books displayed in one bookcase = $No.\ of\ shelves\ in\ 1\ bookcase\times\ No.\ of\ books\ in\ each\ shelf$

Total number of books displayed in one bookcase= $5\times 22=110$

Total number of bookcase required = $\frac{total\ no.\ of\ books}{Number\ of\ books\ displayed\ in\ 1\ bookcase}$

Total number  of bookcase required = $\frac{943}{110} =8\frac{63}{110}$

So, 880 books can be displayed in 8 bookcases. and for the remaining 63 books we also require one more bookcase. Therefore, the total number of bookcases needed are 9.
