### Re: Problem 247

From S 2 you can draw a line from that meets the y-axis and goes through S 12 for example. I assume you mean the shortest line though which must then be perpendicular to the y-axis and parallel to the x-axis. A quicker way of saying "perpendicular to the y-axis and parallel to the x-axis" would be ...

### Re: Problem 247

Draw a horizontal line from (anywhere inside) S

_{2}to the Y axis. How many squares do you cut through? Just one.*That's*the sense in which we mean "to the left".- Thu May 07, 2009 8:19 pm

*R(d)*is the number of resilient proper fractions, divided by

*d*-1.

"Proportion" would have been a better word than "ratio".

### Re: Euler forum

Our current approach to this is to produce those PDF files you see in the right-hand column of http://projecteuler.net/index.php?section=problems (at least for the earlier-numbered problems). One constraint imposed upon us is access control: the PDF should be available only to those who have solved ...
