A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 10000, exactly as in the question.
7209*10000 = 72090000.

13/10000, as a decimal = 0.0013

9753/10000 = 9753 ÷ 10000 = 0.9753
10000.00
Nowhere. 10000 is an integer and requires no decimal number.
First write the decimal part as a fraction: 0.6241 = 6241/10000. This does not reduce any further. You can write a mixed number, i.e. 5 and 6241/10000, or add 50000 to the numerator (5 = 50000/10000) to get an improper fraction, 56241/10000 (which also doesn't reduce).
Expressed as a decimal, 9/10000 is equal to 0.0009.
10 thousandths or 1/10000 is written as 0.0001 as a decimal.
1.08% is 108/10000 as a fraction, and 0.0108 as a decimal.
