In our own planet Earth, 361,419,000 square kilometre of area is covered with water and 148,647,000 square kilometre 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 :

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
