It is also a decimal number, specifically a terminating decimal, where the digits after the decimal point eventually end.
Is 1.25 a real number?
Yes, it is. Moreover, it is also a rational number. 1.25 * 4 = 5, so 1.25 = 5/4. All rational numbers are real numbers, so 1.25 is real. Any number you can think of, using decimal notation is real. Real numbers are allowed to have an infinity of digits (behind the decimal point).
Where do you find decimal numbers in real life?
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.

Is an irrational number a number that is represented by a nonrepeating decimal?
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.
Is negative one-half a real number?
Yes, -1/2 or -0.5 is a real number. It is also a rational number and a nonrepeating decimal rational number. All negative and positive numbers as well as zero are real numbers. The real numbers also includes the irrational numbers.
