Answer:
[tex] \red{ 1 \: : \: 12500}[/tex]
Step-by-step explanation:
First, let us convert these given scales in to same units. We can convert both into cm. As 8cm is already in centimeters, first let us convert 1km into centimeters.
[tex]lkm \rightarrow1000m \\ lkm\rightarrow(1000 \times 100)cm \\1 km\rightarrow100000cm[/tex]
Now let us write these given two scales as a ratio.
[tex]8cm \: : \: 1km \\ 8cm \: : \: 100000cm \\ 8 \: : \: 100000[/tex]
To write the answer in its simplest form let us divide both scales by 8.
[tex]1 :12500[/tex]
