There are an infinite number of decimals between 1.2 and 1.3

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 1213, exactly as in the question.

There are an infinite number of numbers between 12 and 13. decimals, fractions and irrational numbers
13 is the only prime number between 12 and 16.
It is (12 + 13)/2 = 25/2 = 12.5 or 12½
13
13/10. 1.2 = 12/10. 1.5 = 15/10. The denominators are the same and 13 is between 12 and 15 so 13/10 is a valid answer.
There is no decimal number for the binary number 13 because 13 cannot be a binary number.
13/12 = 1.08333

12 is the Integer part. Leave that alone. Next, focus on the decimal part, which is .13. Turn that into a fraction. .13=13/100. That cannot be reduced. Therefore, 12.13 = 12 and 13/100.
13/12 = 1.0833... recurring.
