When two fractions that are 1/16th different are expressed one of these two fraction is expressed in 16ths the other in 8ths
The sum of the numerators of these two fractions is a number that can be
Expressed as a metric number that would be in the mid range of the two fractions
Example: 9/16 and 5/8 9 plus 5 equal 14
coincidentally a 14 mm wrench is little bigger than 9/16 and little smaller than 5/8
Practical application of this law: calculation of wrench conversion from us standard to metric
