Final answer:
To find the ratio of the area of land to the area of water in the Southern hemisphere, we need to know the total area of the Southern hemisphere. Assuming the Southern hemisphere covers 50% of the Earth's surface.
Step-by-step explanation:
To find the ratio of the area of land to the area of water in the Southern hemisphere, we need to know the total area of the Southern hemisphere. Assuming the Southern hemisphere covers 50% of the Earth's surface, the total area of the Southern hemisphere is 50% of the total Earth's surface area. the total area of the Southern hemisphere is 50% of the total Earth's surface area.
Given that 20% of the Southern hemisphere is land, the ratio of the area of land to the area of water can be calculated as follows:
Area of land = 20% of 50% of the Earth's surface area = 0.2 * 0.5 * Earth's surface area
Area of water = 50% of the Earth's surface area - Area of land
Finally, divide the area of land by the area of water to get the ratio.
