cwrw238 · Answer

the fraction of other ingredients is  11/31

so for 60 lbs bread you need  660  / 31 
convert this to a mixed fraction

anonymous · Answer

it would be 21 9/31 in a mixed fraction

anonymous · Answer

20 + x = 31.
Here x is the other ingredients.
therefore x = 11.
as such to get one pound of bread, we must divide the 11 by 31 because 11 lbs of other ingredients make 31 lbs of bread.

so 11/31 times 60 lb of bread will be the total of other ingredients.
