Answer:
80 of the 1200 frogs have spots.
Explanation:
I think you forgot the rest of the question here. But hopefully I gave you the information you were looking for. You find this by dividing 1200 by 180 to see how many of the 180 frog fit into the population, then multiply that number by 12 to see how many of those have spots.
If you find the rest of the question somewhere and its not asking for this just tell me and I will happily find the answer for you.
