=#31 9/32# pounds are ripe.

Explanation:

If #1/8# of the case is NOT ripe, then #7/8# ARE ripe.

So we are actually being asked to find #7/8# of #35 3/4# which is done by multiplying.

#7/8 xx 35 3/4" "larr# change to improper fractions

#=7/8 xx 143/4" "larr# multiply straight across

#=1001/32" "larr#change back to a mixed fraction

=#31 9/32# pounds are ripe.

It is common practice to answer a question in the same format as was given.
