Subject: Re: Re: gallons; ratio and proportion.
Regarding my last post of this date, you can use ratio and proportion to solve many of these type problems. For example, to find out how many liters in a gallon, get a can of diet soda or bottled water and use the data on the can or bottle to determine how many liters in a gallon. For example, a can of diet soda is 12 ounces and 355 ml. You need to know one fact such as 128 ounces in a gallon. 12/128 = 355/x. Solve this problem and you get; x=3787 or 3.787 liters. The dictionary lists the actual answer as 3.785. For water, one gram of water is = to one ml.
