Ailaena Posted August 27, 2008 Share Posted August 27, 2008 [5/8 (1+3/8)] x 17 = 935/64 as you wrote it. Did I miss something? Do you need it worked out? Quote Link to comment Share on other sites More sharing options...
hmsch4me Posted August 27, 2008 Author Share Posted August 27, 2008 They worked it like this: [5/8(1+3/5)] x 17 = 5/8 (8/5) x 17 = 1 x 17 = 17 I think they made an error - they subtracted the fractions instead of added? Quote Link to comment Share on other sites More sharing options...
Jane in NC Posted August 27, 2008 Share Posted August 27, 2008 [5/8 (1+3/8)] x 17 [5/8(1+3/5)] x 17 You have given two different problems! Jane Quote Link to comment Share on other sites More sharing options...

I think this is right. 1 3/5 becomes 8/5, then multiplied with 5/8, they cancel each other out to get an answer of 1. 1x17=17. Quote Link to comment Share on other sites More sharing options...
hmsch4me Posted August 27, 2008 Author Share Posted August 27, 2008 the answer book lists the problem as [5/8(1+ 3/5)] x 17 and the student book has the problem as [5/8(1+ 3/8)] x 17! Quote Link to comment Share on other sites More sharing options...
