I assume you mean an whole number weight from 1 to 40 kg.
Answer: 27 kg 9 kg 3 kg 1 kg
To weigh 1 kg, that's obvious. To weigh 2 kg, put 3 kg on one side, 1 kg on the other. Put your object with the 1 kg weight and make it balance. To weigh 3 kg, that's obvious To weigh 4 kg --> 3 kg + 1 kg To weigh 5 kg --> 9 kg on one side, 3 kg + 1 kg on the other To weigh 6 kg --> 9 kg vs. 3 kg. To weigh 7 kg --> 9+1 kg. vs. 3 kg. To weigh 8 kg --> 9 vs. 1 9 --> 9 10 --> 9 + 1 11 --> 9 + 3 | 1 12 --> 9 + 3 13 --> 9 + 3 + 1 14 --> 27 | 9 + 3 + 1 15 --> 27 | 9 + 3 etc.
You should be able to follow the pattern all the way to 40 kg. I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
