**A container with Bottle A placed in it has a mass of 4.27 kg. An identical container with Bottle B placed in it has a mass of 6.58 kg. The mass of Bottle A is 1/3 that of Bottle B. What is the mass of the Bottle A? Give your answer correct to 2 decimal places.Solution**

Bottle A --> 1 unit

Bottle B --> 3 unit

Container + Bottle A (1 unit) --> 4.27 kg

Container + Bottle B (3 units) --> 6.58 kg

3 units - 1 unit --> 6.58 kg - 4.27 kg

2 units --> 2.31 kg

1 unit --> 2.31 kg divided by 2 units = 1.155 kg

1.155 kg --> 1.16 kg correct to 2 decimal places

**Answer: 1.16 kg**
