Yes, However, it is not defined that way. It is defined as a number that cannot be expressed precisely as a ratio of two real numbers (a fraction). But that is equivalent to a non-repeating decimal.

That already is a decimal.

yes, it is irrational. An irrational number can defined as a number that can not be expressed as a finite nor a repeating decimal.

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.

Decimal numbers cannot be defined as either odd or even.

A decimal number is not an integer. An integer is a number that is not a fraction, and decimal numbers are decimal fractions.

No. A whole number is a number with no fractional (decimal) part. Therefore a decimal number can not be a whole number. Another view: 35.0 is a whole number AND a decimal. The fact that a number is a decimal does not automatically require it to have a fractional part. Even 35 is a decimal number (without a decimal point).

A decimal is a way of representing a number. There is no number after a number.A decimal is NOT a decimal point.

No, 0.326 is not a whole number. Whole numbers are defined by being integers, or numbers without a value (other than 0) past its decimal place.

It is a terminating decimal.

e is defined as the limit of (1 + 1/x)^x as x approaches infinity. It is an irrational number. The decimal approximation is 2.71828183

You make a fraction out of a decimal by looking at the number before the decimal, and then you look at the number(s) after the decimal.

The difference is that all whole numbers are decimal numbers, but not all decimal numbers are whole numbers. For example a whole number such as 1 is a decimal number but a decimal number such as 1.5 is not a whole number.
