Question

Convert from DMS (degrees, minutes, seconds) to decimal form (degrees)

Answer 1

All I remember is:  1° (degree) = 60' (minute) = 3600" (second) and use the given numbers to put on the..... d° m' s"........dd = d + m/60 + s/3600

1) 118°44'15" => 118/1 + 44/60 + 15/3600 = 118.7375 

same thing with 
2) 48°30'36" => 48 + 30/60 + 36/3600 = 48.51
