Answer:

24.9 / 93   by weight    or     1 gal /31 lb   = 1/31  gal/lb

Step-by-step explanation:

Water weighs approx 8.3 pounds per gallon

3 gal * 8.3 pound/gal = 24.9 pounds

water to cement then becomes

   24.9 / 93         ( or  83/310)  

Or maybe you just want    3 gal / 93 lb  

   =  1 gal /31 lb
