The answer cannot be given, because five eighths times three is not a distance, it's just a number. So for part of your question you might as well ask "What's 5/8*3: answer in rowan ash trees and Baseball caps and fractions of a baseball cap".
And if you question was intended to be "2.54 yards plus 7 feet, 3 and five eighths inches, times three; answer in feet, inches and fractions of an inch"... well, it wasn't. Syntax error in Line 1. (^_^)

3/8 or three-eighths. Anything multiplied by one is itself.

45/8
8/3
