ow many of the perfume bottles in Tiffany's collection are made of crystal?
1 answer:
To find the number of perfume bottles that are made of crystal, multiply 99 by 2/3.
An easy way to do this in your head is to divide 99 by 3, and then multiply it by 2.
99/3=33
33*2=66
66 bottles in Tiffany's collection are made of crystal.
