You can first assume that the number of candies in Cocoa is x, then the number of small candies is 7x, and two people per *** have (7+1) = 8x candies. Two people have the same number. Then everyone has 8/2=4x pieces of candy. So the number of candies Xiaoxiao gave to Cocoa was: 7x-4x=15 3x=15 x=5 The answer is that Cocoa originally had 5 candies. Hope it will be adopted.
