Answer :
Final answer:
This problem is a ratio problem involving weights and bags of rice. The weight of 3 bags of rice is approximately 92 kg, and there's likely a mistake in the question, because around 21 bags would be required to make 644 kg.
Explanation:
To solve this math problem involving weights and bags of rice, it's important to remember that this is a ratio problem. With the given information, we know that 15 bags of rice weigh 460 kg. Therefore, you divide 460 kg by 15 to find the weight of one bag. This gives you approximately 30.67 kg per bag.
For the first part of your question, you want to determine the weight of 3 bags. Multiply 30.67 kg (the weight of a single bag) by 3. This results in 92.01 kg, which rounds to 92 kg (option A).
For the second part, to find out how many bags will weigh 644 kg, divide 644 kg by the weight of a single bag (30.67 kg). This results in approximately 21 bags. However, as this isn't an option, maybe there's a typographical error in your question. Please double-check your problem.
