Answer 1

I'm not entirely sure what you are asking.

Percentages all have to add up to 1 or in this case 100, so this problem has some errors or missing information.

Talk to your teacher for help.

Answer 2

Percentages of water of various types:

97% salt water

less than 3% is fresh water

2.7% useable fresh water (not trapped in glaciers, etc)

0.3% drinkable water

Answer 3

Dissolved minerals? Dissolved gases?

Your question is very unclear.
