First, we need to determine how many stickers Juan has after giving 16 to his sister.
Starting with 52 stickers: 52 - 16 = 36 stickers remaining.
Now, Juan shares the remaining 36 stickers equally among his 3 friends.
To find out how many stickers each friend gets, we divide the remaining stickers by the number of friends: 36 รท 3 = 12.
Therefore, each friend gets 12 stickers.
