square kilometre of area is covered by land. Find the approximate ratio of area covered with water to

area covered by land converting these numbers into scientific notation.​

Answer 1

Answer:

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

Area covered by land = 148,647,000 square kilometre

Ratio = 361,419,000 / 148,647,000

Ratio = 12:5

Area covered by water in standard notation = 3.61419 × 108

Area covered by land in standard notation = 1.48647 × 108
