Question

The volume of salt water on earth is 38214 million cubic kilometres and that of fresh water is 1386 million cubic kilometers. Tell the ratio of fresh water to salt water on earth? what is the percentage of fresh water on earth? And the percentage of salt water prove that is7:198?

Answer 1

Answer:

7:193 , 3.5%

Step-by-step explanation:

fresh water : salt water

= 1386 : 38214

= 154 : 4246 =14 : 386 = 7 : 193

% of fresh water

=7/ 200 *100 = 3.5%

Answer 2

Answer:

⟹ 96.5%

Step-by-step explanation:

Volume of the oceanic water in the earth = 38214 mil. Cu. Km.

Volume of the fresh water in the earth

⟹1386 mil. Cu. Km.

∴Ratio of fresh water and oceanic water

$⟹ \frac{1386}{38214} = \frac{7}{193}$

∴Ratio of both the water = 7 : 193.

∴Total part of fresh water and oceanic water

$⟹7 + + 193$

$⟹200$

Hence, Percentage of fresh water

$⟹ \frac{7}{200} \times 100\%$

$⟹ \frac{7}{2} = 3.5\%$

And percentage of oceanic water

$⟹ \frac{193}{200} \times 100\%$

$⟹ \frac{193}{2} \%$

$⟹96.5\%$
