I am looking for dividers to order a card collection. I find some on a website but I really don't understand the dimensions: 2-11/16" x 3-13/16".
Is it (2*11/16)" x (3*13/16)"? It would be rather complicated...
Thanks in advance for your help.

4Given the size of a playing card, I would imagine that 2-11/16" means two and eleven sixteenths of an inch, i.e. 2.6875". How much simpler things would be if everyone switched to the metric system...!– AndyTApr 21, 2015 at 11:37

2@AndyT, I don't see how 68-21/80 mm would be any better, or did you mean "decimal notation" when you said "metric"?– ikegamiApr 21, 2015 at 12:58

1@ikegami - yes and no. I do mean that things would be simpler in decimal notation. But using sixteenths of an inch is very common in imperial (or "US units"). Because the metric system is based on powers, it lends itself incredibly well to decimal notation.– AndyTApr 21, 2015 at 14:25

The " in 2-11/16" denotes inches. The number of inches is written using a common notation for representing improper fractions using only ASCII characters. The represented fraction is
2-11/16" means "two inches and eleven-sixteenth", so the number of inches is actually 2+(11/16) = (2*16+11)/16 = 2.6875, or about 68.3 mm.
Similarly, 3-13/16" means 3.8125 inches, or about 96.8 mm.
2-11/16" x 3-13/16" means 2 and 11/16 inches by 3 and 13/16 inches, or 2.6875 inches x 3.8125 inches. This works out to be about 68.2625mm x 96.8375mm. For reference Magic cards are about 63mm x 88mm.
