Answer 2

Given,

Find the ratio of 400 km to 40000 m.

Solution,

$\[ = \frac{{400km}}{{40000m}}\]$

Know that, $\[1km = 1000m\]$

$\[ = \frac{{400 \times 1000m}}{{40000m}}\]$

$\[ = \frac{{400 \times 1000}}{{40000}}\]$

$\[ = \frac{{40}}{4}\]$

$\[ = \frac{{10}}{1}\]$

Hence the ratio is $\[10:1\]$
