Answer:
1) 6(1/2)
2) 8(4/5)
Explanation:
1) 7 - 1/2 = 7/1 - 1/2 = 14/2 - 1/2 = 13/2 = 6(1/2)
2) 11(2/5) - 2(3/5) = 57/5 - 13/5 = 44/5 = 8(4/5)
Distilling ocean water would be a good solution to meet this community's water needs because it will prevent some water borne diseases such as cholera, diarrhea, typhoid etc.
<h3>
Importance of water distillation</h3>
Water Distillation Systems has several advantages and some of the advantages include;
- It removes waterborne biological contaminants such as bacteria, viruses, organic and inorganic chemicals, heavy metals, etc
- It makes the water fit for consumption
Thus, distilling ocean water would be a good solution to meet this community's water needs because it will prevent some water borne diseases such as cholera, diarrhea, typhoid etc.

The compound HClO4, when placed in water, will dissociate into the ions, H+ and ClO4-. Therefore, the 2.0 M solution will also form 2.0 M H+. The pH is calculated through the equation,
pH = -log[H+]
Substituting,
pH = -log[2] = -0.3
Thus, the pH of the solution is -0.3.
