Question

Ratio of land water on earth is 1:2.If the ratio of land and water on northern hemisphere is 2:3. Find the ratio in southern hemisphere

Answer 1

Answer:

4:11

Step-by-step explanation:

Ratio of Land : water  = 1:2

If Land = L

Water = 2L

Total = L + 2L = 3L

Northern hemisphere = 3L/2

Land : water = 2: 3

2k Land  & 3 k water

2k + 3k = 5k

5k = 3L/2

2k = Land on Northern = (3L/2)(2/5) = 3L/5

3K = water on Northern = (3L/2)(3/5) = 9L/10

Land on Southern = L - 3L/5  = 2L/5

Water on Southern = 2L - 9L/10  =  11L/10

Ratio of Land : water on southern

= 2L/5 :  11L/10

= 4 : 11
