It tells you the value (and sign) of the number.
27.9 IS a decimal number. You can tell it is a decimal number because it has a decimal point (.).
When a decimal can't be expressed as a fraction then it is an irrational number.
If it is a terminating or recurring decimal then it is not irrational. If it is an infinite, non-recurring decimal, it is irrational.
It is difficult to tell when a number has two decimal points in it.
Near enough the exact value of the number. Logarithms, for positive numbers, have are invertible.
It is a number with a decimal point. It is not necessarily a decimal number because 24 (no decimal pont) is a decimal number.It is a number with a decimal point.

It is difficult to tell in a number with two decimal points!
It is had to tell with a number containing two decimal points.
If the number is an integer, then you cannot tell, but it does not matter: the decimal and other representations are the same. If the number is not an integer, then a decimal will have a decimal point (a full stop) followed by one or more digits. A non-decimal will have a rational element (a/b) with some integers a and b, both non-zero)
no because 969 is an odd number and 2 is an even number, also you can tell if you divide 969 by two your answer is a decimal point (484.5) and in order for it to be divisible by 2 it can not be a decimal it has to be a whole number..
three decimal four
Yes. You can tell because there is a finite number of decimal places. 0.91 = 91/100 which is a rational number.
