If 29.2% of the earth is land, what percentage is water?

Explanation:
Earth’s surface is made up of land and water, and together they add up to 100%. If land accounts for 29.2%, water must be the remaining portion. So 100% minus 29.2% equals 70.8%. This aligns with the common fact that oceans cover about 71% of the planet. The other options don’t fit because 29.2% is the land portion, not water; 50% isn’t the remaining portion; and 100% would mean all of Earth's surface is water (or all land), which isn’t the case.
