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".

There will be a 25 grams left after 3240 years.
The half-life of Radium-226 is 1620 years. If we divide 3240 by 1620 the answer is 2. So that means the amount of Radium-226 will divide in half twice.
100 / 2 = 50 / 2 = 25
