In our planet Earth 361,419,000sq km of area covered with water and 148,647,000sqkm is covered by land. Find the approximate ratio of area covered
with water to area covered by land by converting these numbers into scientific
notations

The Ratio of area covered  with water to area covered by land is 2.43 * 10⁰

Area covered by water = 361,419,000 km²

Area covered by land = 148,647,000 km²

Ratio of area covered  with water to area covered by land is:

Ratio = 361,419,000 km² / 148,647,000 km² = 2.43 * 10⁰

The Ratio of area covered  with water to area covered by land is 2.43 * 10⁰
