rational numbers
Rational numbers are numbers that can be expressed as a ratio or a fraction of two integers, where the denominator is not zero
Rational numbers are numbers that can be expressed as a ratio or a fraction of two integers, where the denominator is not zero. In other words, they can be written in the form a/b, where a and b are integers and b is not equal to zero.
Some examples of rational numbers include 3/4, -2/5, 1/2, 5, and -7.
Rational numbers can be positive or negative, and they can be whole numbers, fractions, or terminating/ repeating decimals. For example, 4 can be expressed as 4/1, and 0.333… can be expressed as 1/3.
Rational numbers can be operated on using addition, subtraction, multiplication, and division, and these operations can also result in rational numbers. For example, if we add 1/2 and 1/3, we get 5/6, which is still a rational number.
It’s worth noting that not all real numbers are rational. Numbers like π (pi) and √2 (square root of 2) are examples of irrational numbers, as they cannot be expressed as a ratio of integers.
