One gallon of water weighs about 8 pounds 5 ounces. Something is carrying 500 gallons of water. What is the weight of the water to the nearest pound?

Question

This is about converting measurements 

Answer 1

1 pound  = 16 ounces

 

8 pounds and 5 ounces = 8 and 5/16 pounds, which is the weight of 1 gallon of water.

 

So 500 gallons of water weighs

 

  500 * ( 8 and 5/16) = 

 

  500 * 133/16 = 66500/16 = 16625/4 =  4156 and 1/4 pounds

 

                                                           = 4156 pounds and 4 ounces  ,   as 1/4 lb = 4 ounces

 

                                                            = 2 tons 156 pounds and 4 ounces

 

To the nearest pound 4156

Answer 2

8 lbs 5 oz = (8 + 5/16) lbs = 133/16 lbs

 

500 x 133/16 = 4156.25 lbs or 4156 lbs, 4 ozs
