$\dfrac{58}{197}$

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 :-

$\dfrac{\text{Land area}}{\text{Earth's surface area}}$

$=\dfrac{58000000}{197000000}\\\\=\dfrac{58}{197}$

Hence , the fraction of the earths surface is land = $\dfrac{58}{197}$

since 58≈60 and 197≈200

$\dfrac{58}{197}\approx\dfrac{60}{200}=\dfrac{3}{10}$

Another fraction that is close to answer and has a denominator of 10= $\dfrac{3}{10}$
