# A bookshelf is 2.25 m tall and height of each shelf is 25 cm. how many shelves are there?

$Lengthofbookshelf=2.25m=2\times 100cm+25cm=225cm\phantom{\rule{0ex}{0ex}}Heightofeachshelf=25cm\phantom{\rule{0ex}{0ex}}No.ofshelves=\frac{Lengthofbookshelf}{Heightofeachshelf}\phantom{\rule{0ex}{0ex}}=\frac{225}{25}\phantom{\rule{0ex}{0ex}}=9$
