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.
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)
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.
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.
