1) 27x8=216
20x8=160
7x8=56
160+56=216
2)Train B has travelled more
Train A travelled 6/9 of 81 kilometres which is 54 that's 27 kilometres from 81 kilometres.
Train B travelled more because they travelled ⅞ of 72 kilometres which is 63 kilometres that's 9 kilometres away from 72 kilometres. 9 Is smaller than 27 so the less number is the answer.
3)51.2 divided by 8 is 6.4
8x6=48 and there's 3.2 left and 3.2 divided by 8 is 0.4 so 6+0.4 is 6.4
