Answer:
30%
Explanation:
The local zoo contained 40 exhibits in total. It contained 12 reptile exhibits.
The percentage of the zoo's exhibits that feature reptiles is gotten by dividing the number of reptile exhibits by the total exhibits and then, multiplying by 100:
=> (12 / 40) * 100
= (3 / 10) * 100 = 300 / 10
= 30%
30% of the zoo's exhibits feature reptiles.
