Jill has 11 8 ounces of trail mix write the weight of joe's trail mix as a mixed number

Okay so 11.8 as a improper fraction is 
59
---
 5 
but we want that as a mixed number so how many times does 5 go into 59? 11 times right. s, so far our whole number is 11 but 5 times 11 is 55  so how many remain? well
59 - 55 = 4  so lets write out our fraction 
      4 
11      or 4/5 could be also 8/10s its just simplified 
      5
the bottom number stays the same!
hope this helps explain more clearly:)

Both 11 and 4/5 or 11 and 8/10 are correct answers:)
