Integers and Rational Numbers

An integer is a whole number that can be positive, negative, or zero. Examples include -3, 0, and 5.

A rational number is any number that can be expressed as a fraction $$\frac{a}{b}$$ , where $$a$$ and $$b$$ are integers and $$b \neq 0$$ . Examples include $$\frac{1}{2}$$ and 0.75.

0.5 can be represented as $$\frac{1}{2}$$ .

The decimal equivalent of $$\frac{3}{4}$$ is 0.75.

-2 is greater than -5 because it is closer to zero on the number line.

The absolute value of -7 is 7.

To convert a fraction to a decimal, divide the numerator by the denominator. For example, $$\frac{1}{4} = 0.25$$ .

The number line represents all real numbers, including integers, fractions, and decimals, arranged in order.

The sum of -3 and 5 is 2.

The difference between 4 and -2 is 6.
