Answer 1

The display area occupied by Germany is $\frac{8}{63}$

Explanation

Australia and America occupy $\frac{3}{7}$ and $\frac{4}{9}$ of the display area respectively.

So, the total area occupied by Australia and America is $=\frac{3}{7} +\frac{4}{9} =\frac{27+28}{63}=\frac{55}{63}$

As the total display area is 1 , so the display area occupied by Germany will be:  $1-\frac{55}{63}=\frac{63-55}{63}=\frac{8}{63}$
