Thane Plambeck wrote in part: I'm interested in what people may think of the following math problem from a document entitled "What to Expect on the ISEE." I hope they allowed rulers, with markings, and calculators! And I hope it was really printed to scale (as opposed to what was submitted to the printing company being to scale). With the JPG, who can tell. The "13" looks off the most from the rest (about 1.25 times the "12" as opposed to the expected ratio of 1.083). I printed it and measured to the nearest millimeter to get the following. Of course, I could be off a millimeter in my readings. Other printers or screens could give different results. By varying the aspect ratio, it looks like the "12" can be made to be in line with the "8" and "26", but there is no hope for the "13".
