Final answer:
To calculate the percentage of total downloads that were app 2, we need to know the number of downloads for app 2 and the total number of downloads.
Step-by-step explanation:
To find the percent of total downloads that were app 2, we need to know how many downloads of app 2 there were. Since the question doesn't provide that information, we cannot calculate the percentage accurately.
In order to calculate the percentage, we need to know the number of downloads for app 2 and divide that by the total number of downloads, and then multiply by 100 to get the percentage.
Without the necessary information, we cannot determine the correct answer option.
