A really obvious but interesting questionHi can u plz answer this question. I find it ...well it makes me go #2 20060112 14:54:56
Re: A really obvious but interesting questionConsider a / b. This could be written as a * 1/b. Now let a = 3/2 and b = 1/2. (3/2) / (1/2) "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #3 20060112 18:17:55
Re: A really obvious but interesting questionI think you are right about flipping one of the fractions, only you need to then multiply each side (not divide) Aloha Nui means Goodbye. #4 20060112 22:58:57
Re: A really obvious but interesting questionI don't really know, but let's explain it like this: Name :: Vincent Raider Hawks Gender :: Male Birth Date :: July 4 , 1970 #5 20060112 23:31:01
Re: A really obvious but interesting questionRather than struggle to do it in here, i've knocked up a basic proof thingy. I couldn't figure out how to post it as an image, so here's a link to the image instead: Student: "What's a corollary?" Lecturer: "What's a corollary? It's like when a theorem has a child. And names it corollary." #7 20060116 17:33:20

Re: A really obvious but interesting questionrickyoswaldiow, (s)he's asking:
Not just how. I guess one reason why is because it's hard to divide fractions, but it's easy to multiply them. I don't think that one was ever said. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #10 20060117 02:47:18
Re: A really obvious but interesting questionI think the problem was, anya was flipping one fraction but still dividing them. I was emphasising that you need to multiply it once flipped. Like you say, it's easier to multiply it that way Aloha Nui means Goodbye. #11 20060118 05:14:00
