Question 117880
okay...this doesnt even come out the way i thought it would..please help me 
subtract
8 gal 7 qt
-3 gal 2 qt
_________________ 
  
Lets first deal in qts to start with:

Now we know that there are 4 qts in a gal.  That means there would be 8*4 or 32 qts in 8 gal
So 8 gal 7qts=32qts + 7qts=39qts
And 3 gal 2qts=12qts+2qts=14qts

Now we have:

39 qts-14 qts=25qts Now to convert back to gal

4 will go into 25 6 times with 1 qt left over.  So our answer is:

6 gal and 1 qt or (d)
