DMS form =  12°25'12''.

Step-by-step explanation:

Given :  12.42.

To find : written in DMS form.

Solution : We have given that  12.42.

Multiply 42 by 60 to convert it in to minute

We can write it as  12 + .42(60).

12°25.2'

Rewrite 12°25+.2'

2' = 2 ( 60) to convert minute in to second.

12°25+.2(60)

12°25'12''

Therefore, DMS form =  12°25'12''.
