Answer:

The simplest form ratio is 1  : 50000.

Step-by-step explanation:

To find the ratio of 2 cm : 1 km

Firstly, we need to convert both the quantities into the same unit of measurement.

Now 1 km = 1,00,000 cm

So, now we need to find the ratio of 2 cm :   1,00,000 cm

⇒ The required Ratio is  [tex]\frac{2}{100000} =\frac{1}{50000} [/tex]

Hence, the simplest form ratio is 1  : 50000
