Lizzy: Oliver has two bags of vegetables. Each bag weighs 1/6 as much as James's bag, which weighs 18kg. What is the combined weight of both Oliver's bags?.
Me: Hmmm, let me think. I think this is the detailed solution:
Each of Oliver's bags weighs 18 kg * 1 / 6 = 3 kg. Combined, both his bags weigh 3 kg * 2 = 6 kg. Final answer: 6.
