Answer:
4.84% of trees on the island are poisonous.
Explanation:
The proportion of fruit trees that are poisonous is the number of poisonous fruit trees divided by the total number of trees.
The percentage is the proportion multiplied by 100.
In this question:
60 poisonous trees.
1240 total trees.
60/1240 = 0.0484
0.0484*100 = 4.84%
4.84% of trees on the island are poisonous.
