The mass of one part is 5 4/5 kg, which is 1 1/2 kg less than the mass of the other part. What is the mass of the two parts together?

Weight of one piece 5 4/5 kg = 5.8 kg
Other part weight: 5.8+ 1 whole 1/2 = 5.8 + 1.5 = 7.3 kg
So the mass of the two parts together: 5.8 + 7.3 = 13.1 kg
Answer: 13.1 kg
