Hmm, let me perform a little juggling with the numbers for you.
Ding ding ding! The answer is A. rational number!
Why? Well, a rational number is any number that can be expressed as a fraction, and 1.256 can indeed be written as a fraction. It might not be a whole number or an integer, but it still falls under the realm of rationality. Keep those fractions flowing!
To identify which sets the number 1.256 belongs to, we can go through each set and its definition:
1. Rational number: A rational number is any number that can be expressed as a fraction, where both the numerator and the denominator are integers. To determine if 1.256 is a rational number, we need to check if it can be written as a fraction. In this case, 1.256 can be expressed as 1256/1000, which simplifies to 157/125. Since both 157 and 125 are integers, we can conclude that 1.256 is a rational number.
2. Irrational number: An irrational number is a number that cannot be expressed as a fraction, or it has an infinite and non-repeating decimal representation. Since we already determined that 1.256 can be expressed as a fraction, it is not an irrational number.
3. Integer: An integer is any positive, negative, or zero whole number, including both the positive and negative integers. To determine if 1.256 is an integer, we need to check if it is a whole number.
4. Whole number: A whole number is any positive number, including zero, without any decimal or fractional part. In this case, 1.256 has a decimal part, so it is not a whole number.
From these definitions, we can conclude that the correct answer is:
A. rational number
