Answer:
5 vases
Step-by-step explanation:
Since 3 vases were chipped and 15 were not, that means that 3 in 3+15=45 vases are chipped. So, we can set up a proportion:
3/45 simplifies to 1/15 by the way
1/15 = x/66
x is the number of vases expected to be chipped
1/15 = x/66
Cross multiply
15x=66
x=66/15
x=22/5
x=4 2/5
Since you can't have part of a vase, 5 vases will be expected to chip.
