you fill a water tank with 3.4*10^6 galoons of water. about 6.1% of water is not fresh water.

you fill a water tank with 3.4*10^6 galoons of water. about 6.1% of water is not fresh water.

how many gallons of fresh water is there?

 

The percentage of fresh water is:

100% - 6.1% =93.9%

(93.9/100) x 3.4 x 10^6=3,192,600=3.1926 x 10^6 gallons of fresh water in the tank.

If 6.1% IS NOT fresh water, then 100% - 6.1%  IS freshwater = 93.9%

 

93.9% x 3.4 x10^6 =  .939 (3.4) x 10^6 = 3.1926 x 10^6 gallons =  3,192,600 gallons

Percentage of Fresh water = 100%-6.1% = 93.9%

3.4*10^6*93.9%

= 3192600

There are 3192600 gallons of fresh water
