Convert 17.47° to degrees, minutes, and seconds..
never [62]
For this question, this might help.
17.47 degrees is 17 + 0.47 degrees
If you are using minutes instead of decimal degrees, multiply the fraction by 60. So,

0.47 degrees * 60 minutes per degree= 28.2 minutes

Now you have 17 degrees 28.2 minutes but you can replace fractions of a minute with seconds
 
0.2 minutes * 60 seconds per minute= 12 seconds

So the answer for 17.47º is equal to 17º 28' 12".

I hope this helps.
