 Folding a rectangle to preserve the aspect ratio 2015-05-09 From Anna:If you fold a rectangular piece of paper in half and the resulting rectangles have the same aspect ratio as the original rectangle, then what is the aspect ratio of the rectangles?Answered by Penny Nom. A sixfold increase 2007-10-24 From Fred:If I have \$500 and it grew to \$3,000, what is the correct description of the increase? Is it a sixfold increase (sextupled), or a fivefold increase (quintupled)? When I divide \$3,000 by \$500, the result is six, therefore, a sixfold increase?Answered by Stephen La Rocque. A rectangular sheet of paper is folded along the diagonal 2007-09-01 From Amit:A rectangular sheet of a paper with dimensions a and b is folded along its diagonal. What is the area of the overlapped region?Answered by Harley Weston. Folding a sheet of paper 2005-12-15 From Victoria:The current problem is to take a normal 8 1/2 x 11 sheet of paper, take a corner and fold it to meet the opposite corner, and (without actually measuring) produce a formula to describe the result fold/crease.Answered by Penny Nom. Manifolds 2001-05-14 From Thierry:Maybe you could help me, because I have serious problems for the translations of an English mathematic word which is "MANIFOLD". It's impossible to have a clear translation in French. Do you have a solution?Answered by Claude Tardif. Folding a page 2000-03-01 From Krista Bischoff:One corner of a page of width a is folded over and just reaches the opposite side. Express L, the length of the crease, in terms of x and a. I can't get the picture to copy to this form so I guess I will have to try and describe the picture the best that I can. The top right hand corner is folded to the left side, almost half way down. The width of the paper is a ( the width of the bottom part which is not folded.) The creased side is L and the part shorter part of the folded area is x (the part that would have been the top right of the original piece.) Answered by Chris Fisher.
