The ratio of land to water in the northern hemisphere is about 1:1.5 or 2:31.
Thus the percentage of water cover out of total land area in the northern hemisphere can be found the following way 3/(2+3) = 0.6 or 60%.
The total surface area of the northern hemisphere is (255,036,000 km2)2. 60% of this area is 0.6 X 255,036,000 = 153,021,600 km2 = the amount of area covered by water in the Northern Hemisphere.
The percentage of land cover out of total land area in the northern hemisphere can be found the same way 2/(2+3) = 0.4 or 40%. 40% of this area is 4.6 X 255,036,000 = 102,014,400 km2 = the amount of area covered by land in the Northern Hemisphere.
Notice the ratio of land to water is 102 million km2 to 153 million km2, very close to the 1:1.5 ratio we began with.
The ratio of land to water in the south is about 1:41.

About 61% of the northern hemisphere is covered by oceans.
Southern Hemisphere
The four Hemispheres of the Earth are the Northern, Southern, Eastern and Western hemispheres.
By continents, cities, states, villages, roads, oceans, hemispheres, etc.
By continents, cities, states, villages, roads, oceans, hemispheres, etc.
The earth's four major oceans are the Pacific, Atlantic, Indian, and Arctic. The continent to the south of these four oceans is Antarctica.
You can't have four hemispheres on one sphere unless they overlap. The usual divisions are into the Northern and Southern hemispheres (divided, sensibly enough, by the equator) or the Eastern and Western hemispheres (divided by the great circle which contains the Prime Meridian).
the pacific ocean
The Pacific and Atlantic Oceans are both in all four hemispheres.
Hemispheres: Eastern, Northern, Southern, and Western. Continents: Africa, Antarctica, Asia, Australia, Europe, North America, and South America. Oceans: Atlantic, Arctic, Indian, Pacific, and Southern.
Pacific, Atlantic and Indian Oceans are all in both hemispheres.
