To find the weight of each piece of cake, you need to divide the total weight of the cake by the number of pieces. In this case, the cake weighs 2.5 kg and there are 25 pieces.

To calculate the weight of each piece, divide the total weight of the cake (2.5 kg) by the number of pieces (25):

Weight of each piece = Total weight of the cake ÷ Number of pieces

Weight of each piece = 2.5 kg ÷ 25

Weight of each piece = 0.1 kg

Therefore, each piece of cake will weigh 0.1 kg.
