We have been given that the surface area of the earth is approximately 197000000 square miles.
Also the land area of the earth is given by 58000000 square miles.
Therefore, the fraction of the earth surface is land is given by
[tex]\text{Required fraction }= \frac{\text{Land surafce area}}{\text{Total surface area}}\\ \\ \text{Required fraction }= \frac{58000000}{197000000}[/tex]
On simplifying it, we get
[tex]\text{Required fraction }= \frac{58}{197}[/tex]
