Hello. Nobita and Nini differ 10 starfish. If Nobita's 10 can be handed over, then Nobita and Nini's numbers will be the same. Then they divided the 10 starfish equally, and Nobita got five and Nini got five, so Nobita and Nini got the same number of starfish, that is, Nobita gave Nini five starfish, and their numbers were the same.
