Answer:
The percentage of the students picked a vanilla cupcake is 75%.
Explanation:
Given that Anita brought chocolate and vanilla cupcakes to school for her birthday, and 64 students decided to take a cupcake, and 48 of them picked vanilla, to determine what percentage of the students picked a vanilla cupcake the following calculation must be performed:
64 = 100
48 = X
48 x 100/64 = X
4,800 / 64 = X
75 = X
Therefore, the percentage of the students picked a vanilla cupcake is 75%.
