Give the step-by-step reasoning process and then the final answer. Chelsea has 24 kilos of sugar. She divides them into 4 bags equally. Then one of the bags gets torn and half of the sugar falls to the ground. How many kilos of sugar remain?
Each bag has 24 / 4 = 6 kilos of sugar. 6 / 2 = 3 kilos of sugar falls to the ground. 24 - 3 = 21 kilos of sugar remains.
The final answer: 21.
