I need to buy some hose for an old washing machine. I plan top just buy
some plastic tubing called Dairy hose (used for cow milking machines). I
am almost helpless when it comes to math.

The original hose is listed as .875 inch ID.
But that dairy hose is sold as a fraction, such as 3/4". (I know 3/4" is
..750). What is .875 as a fraction?

(I'm guessing around 7/8", but that's just a guess).

Thanks for all help.
