{{{(10.46/94)(dollars/ounce)}}}


{{{0.111(dollars/ounce)}}}-------which, to the nearest cent, is 0 dollars or 0 dollars and 0 cents.


Fix your problem description.  The money quantities given were not stated as being ratios, but the complete information might have been omitted, and those were meant as prices, in dollars per ounce.  The description in the posting gave only money values as just dollars.
