Re: [math-fun] Mixed numbers?

="rwg" <rwg@sdf.org> Would you believe carpenters use "five quarter round" molding? =William R. Somsky How about carpenters? "I need this board cut to be three feet, seven and five-eights inches long."

Oh, those wacky carpenters. Their dimensionality for nail length is in money units, specifically pennies. The measure was once the price per hundred nails of a given length... but actually it was per long-hundred, that is, per 120. Notwithstanding that there are 240 pennies per pound sterling, some fifteenth century structures still stand. Coincidentally today I measured my hat size; I'm a 7 3/8. Happy holidays!
