If the diameter of the Sun is $1.4\times10^9$ m and that of the Earth is $1.275\times10^4$ km. Compare the two.

Given:

The diameter of the Sun is $1.4\times10^9$ m and that of the Earth is $1.275\times10^4$ km.
To do:

We have to compare the two.

Solution:

We know that,

$1\ km=1000\ m$ 
Therefore,

Diameter of the Sun $=1.4\times10^9$ m.

Diameter of the Earth $=1.275\times10^4$ km$=1.275\times10^4\times10^3$ m

$=1.275\times10^7$ m

This implies,

Diameter of the Sun$\div$Diameter of the Earth$=\frac{1.4\times10^9}{1.275\times10^7}$

$=110$

Diameter of the Sun is 110 times the diameter of the Earth.
