Walt: add and subtract decimals
Again this week we have been focusing on adding and subtracting decimals. Here are one of the solutions I did last week. On Monday, Lanzie walked 6.9 kilometres. On Tuesday, he walked 1.9 kilometres less than he had walked on Monday. How far did Lanzie walk on Tuesday?I think it is 5.0 for example if you were to add 1.9 to something to get to 6.9 it is 5.0.
