Are rational numbers positive or negative?

Rational numbers can be positive, negative, or even zero. Rational numbers encompass all numbers that can be expressed as a fraction of two integers, so they cover a wide range of values across the number line.

What are some examples of rational numbers?

Some examples of rational numbers include integers (such as -2, 0, 5), fractions (such as 1/2, -3/4), terminating decimals (such as 0.75, -1.2), and repeating decimals (such as 0.333..., 0.757575...). Rational numbers are any numbers that can be expressed as a ratio of two integers, where the denominator is not zero.

What is the definition of a rational number?

A rational number is a number that can be expressed as a fraction where the numerator and denominator are both integers, and the denominator is not zero. In other words, a rational number is any number that can be written in the form a/b, where a and b are integers.

How are rational numbers represented on a number line?

Rational numbers are represented on a number line by placing them at their corresponding point, where each point represents the value of the rational number. The number line is divided into equal intervals, and rational numbers can be plotted in between these intervals by calculating their numerical value and placing them at the appropriate position on the number line.

Can a rational number be a whole number or an integer?

Yes, a rational number can indeed be a whole number or an integer. Whole numbers are a subset of integers, and integers are a subset of rational numbers. Whole numbers are non-negative integers, including 0, while integers are positive and negative whole numbers, along with 0. This means that every whole number and integer can be represented as a fraction with a denominator of 1, making them rational numbers.

Are all decimal numbers considered rational numbers?

No, not all decimal numbers are considered rational numbers. Rational numbers can be written as a fraction of two integers, while decimal numbers like pi or the square root of 2 cannot be expressed as a fraction and are considered irrational numbers.

Can rational numbers be expressed as fractions?

Yes, rational numbers can always be expressed as fractions. This is because a rational number is defined as any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. In other words, a rational number can always be written in the form of a/b, where a and b are integers and b is not zero.

Is zero a rational number?

Yes, zero is a rational number because it can be expressed as the quotient of two integers, where the denominator is not equal to zero. In this case, zero can be written as 0/1, which meets the criteria for a rational number.

Can irrational numbers be located on a number line?

Yes, irrational numbers can be located on a number line. A number line represents all possible real numbers, both rational and irrational, in order from left to right with increasing value. For example, the square root of 2 (?2) or pi (?) are examples of irrational numbers that can be located on a number line, even though they cannot be expressed as a simple fraction.

Are rational numbers dense on the number line?

Yes, rational numbers are dense on the number line, meaning that between any two rational numbers, there exists another rational number. This property of denseness implies that rational numbers are closely packed on the number line and that there are infinite rational numbers between any two distinct rational numbers.
