Question

Earth has a surface area of approximately 197,000,000 square miles and a total land area of approximately 58,000,000 square miles. What fraction of the earths surface is land? Write another fraction that is close to your answer and has a denominator of 10

Answer 1

The desired fraction is 58/197, or approx. 0.29. This is equivalent to 29/100, or 30/100, or 3/10.

Answer 2

Answer:
`(58)/(197)`

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 :-

`\frac{\text{Land area}}{\text{Earth's surface area}}`

`=(58000000)/(197000000)\\\\=(58)/(197)`

Hence , the fraction of the earths surface is land =
`(58)/(197)`

since 58≈60 and 197≈200

`(58)/(197)\approx(60)/(200)=(3)/(10)`

Another fraction that is close to answer and has a denominator of 10=
`(3)/(10)`
