Geometry (calculating degrees,minutes)

[Pearce_09]

this might be a simple question
but i do not know how to convert degrees to degrees,minutes
say if i have
74.39 degrees it converts to 74 degrees 24 minutes
i do know that
1 minute = 1/60 degrees... please help

 

[Gokul43201]

74.39 deg = 74 deg + 0.39 deg

0.39 deg = 0.39 deg * 60 min/deg = 23.4 min = 23 min + 0.4 min

0.4 min = 0.4 min * 60sec/min = 24 sec

So, 74.39 deg = 74 deg 23 min 24 sec

PS : This would go in Precalc Math.
