The diameter of the moon is approximately one fourth of the diameter of the earth. What fraction of the volume of the earth is the volume of the moon?

Volume of a sphere = (4/3)πr^{3}

Given, diameter of the moon is approximately one fourth of the diameter of the earth

Radius of moon = 1/4 × radius of the earth.

Ratio of their volume

Volume of the moon is 1/64^{th} times the volume of the earth.
