buttercup Posted December 3, 2010 Share Posted December 3, 2010 My dd could not figure out what number or fraction she was supposed to write the prime factorization of. When I looked in the Solutions manual it seems that she was supposed to do that for 144/600. Where did that fraction come from? She was correct in the first part of the problem (14 a.), but she could not figure out what she was supposed to write the prime factorization of and I do not see how 144/600 fits in. Any help in understanding would be appreciated. Quote Link to comment Share on other sites More sharing options...
dani3boys Posted December 3, 2010 Share Posted December 3, 2010 Are you trying to figure out how to solve #14-b, or are you trying to figure out why it is seemingly unrelated to part a? I don't see any relationship between part a and part b if that is what you are asking. I am not the best math person though, so maybe someone else will know better than I do.

cbollin Posted December 3, 2010 Share Posted December 3, 2010 hmmm.. maybe a misprint in your edition? my edition of 8/7, lesson 36, 14b (p. 248) says: Write the prime factorization and reduce: 144/600 so in the student book it did list that fraction.

buttercup Posted December 3, 2010 Author Share Posted December 3, 2010 Thanks Danielle and Crystal! You probably already figured this out Crystal, but I am the one who posted the same question on the MFW boards and you answered me there as well.

cbollin Posted December 3, 2010 Share Posted December 3, 2010 I know. but i was bored and typed over here too. :lol: I almost didn't. I thought, oh, no, she'll think I'm stalking her. :lol: that's still weird that your book was missing the last part of that problem. but, it all works out. I need more sleep and more cleaning....... -crystal Quote Link to comment Share on other sites More sharing options...
