How is it possible? :001_unsure: Thanks. Quote Link to comment Share on other sites More sharing options...
plansrme Posted February 10, 2012 Share Posted February 10, 2012 Do you get the right answer if you use 1000 in place of 100? If not, I suggest checking with the forum at singaporemath.com. Terri Quote Link to comment Share on other sites More sharing options...

vito Posted February 10, 2012 Author Share Posted February 10, 2012 Well, my kid was confused and asked for help. We bought SM three weeks ago, and this is actually the first time I looked into the book closer. The problem #5 has a lot of irrelevant given including this 100 vs. 280.
