sarah can fit 115 books in 2 bookcases at that rate how many bookcases does she need to hold 360 books?

7 book cases

Step-by-step explanation:

Add 115 to itself until you reach past 360 (there is a remainder). 115 added 3 times is 345. 115 books=2 bookcases. So you multiply: 2*3=6. Since there is not enough room for all 360 books in 6 bookcases, you need 1 more, which makes it 7 bookcases.

Answer:115books = 2bookcases

360books=xbookcases

115x=2*360

115x=720

x=720/115

x=6.3 ~ 6bookcases
