It is composite.
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 146, exactly as in the question.
Percent means "out of 100" → 146 % = 146/100 = 73/50 = 123/50 → 146 % = 146/100 = 146 ÷ 100 = 1.46
146 rounded to hundredths would be 146, but could be written as 146.00 to indicate the precision.
Yes, it is.

146.00
This already is a whole number. You don't need to change anything.
8 and 146 over 1000 it's a mixed number with 8 as the whole number 146 as the numerator and 1000 as the denominator
146
100
It is: 146/178 times 100 = 82% rounded

146 rounded to one significant figure becomes 100
146 is not prime. 146 = 2 * 73
