3/8 X 32= 12
1 and 3/8ths is the same as 8/8ths + 3/8ths. This is summed to 11/8ths. Half of that would be 11/16ths.
33 & 3/4. Twice 16 is 32, and twice 7/8 is 14/8 which is 1 & 6/8 (or 1 & 3/4)

In fluorescent tubes the number represents the diameter of the tube. The tubes are measures in 1/8ths of an inch. T8 would be 8/8ths or 1 inch. T5 would be 5/8ths of an inch. Older fixtures took T12 which would be 12/8ths or 1.5 inches.
