0.45 = 45/100. The greatest common factor of 45 and 100 is 5 and dividing both by 5 gives 9/20.

A decimal number is a way of representing a number in such a way that the place value of any digit is ten times that of the digit in the place to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So the decimal for 1720 is 1720 – exactly as in the question.
