Answer: [tex]\dfrac{58}{197}[/tex]
Step-by-step explanation:
Given : Earth has a surface area of approximately 197,000,000 square miles and a total land area of approximately 58,000,000 square miles.
Then fraction of the earths surface is land is given by :-
[tex]\dfrac{\text{Land area}}{\text{Earth's surface area}}[/tex]
[tex]=\dfrac{58000000}{197000000}\\\\=\dfrac{58}{197}[/tex]
Hence , the fraction of the earths surface is land =[tex]\dfrac{58}{197}[/tex]
since 58≈60 and 197≈200
[tex]\dfrac{58}{197}\approx\dfrac{60}{200}=\dfrac{3}{10}[/tex]
Another fraction that is close to answer and has a denominator of 10= [tex]\dfrac{3}{10}[/tex]
