Question

In our own planet Earth, 361,419,000 square kilometer of area is covered with water and 148,647,000 square kilometer of area is covered by land. Find the approximate ratio of area covered with water to area covered by land by converting these numbers into scientific notation

Answer 1

Answer:

Area covered by water = 361,419,000 square kilometre
