Answer:
20 gallons
Step-by-step explanation:
128 times 20 = 2,560 fl oz
convert fl oz to gallons
----------------------------------------
10 fl oz = 0.078125 gallons
100 fl oz = 0.78125 gallons
1,000 fl oz = 7.8125 gallons
----------------------------------------
multiply 7.8125 by 2 to get 15.625
multiply 1,000 by 2 to get 2,000
----------------------------------------
multiply 0.078125 by 6 to get 0.46875
multiply 10 by 6 to get 60
-----------------------------------------
multiply 0.78125 by 5 to get 3.90625
multiply 100 by 5 to get 500
-----------------------------------------
add all of the products to get the final sum
------------------------------------------
15.625 + 0.46875 + 3.90625 = 20 gallons
2,000 + 60 + 500= 2,560 fl oz
