Answer:
To balance 1.5 kg of meat using a beam balance and masses of 0.5 kg and 2 kg, the butcher can follow these steps:
1. Place the 2 kg mass on one side of the balance.
2. Place the 0.5 kg mass and the meat on the other side.
3. Initially, the side with the 2 kg mass will be heavier.
4. Remove the 0.5 kg mass from the side with the meat.
5. Now, the side with the meat will be lighter.
6. Add the 0.5 kg mass back to the same side with the meat.
7. The balance should now be level, indicating that the meat weighs 1.5 kg, as it is balanced against the 2 kg mass and the 0.5 kg mass.
This way, the butcher can balance 1.5 kg of meat on the beam balance using the provided masses.
Hope this helps :)
