Here’s a hint: if you’re working with a number with a long line of different decimals, then your number is irrational! If you’re working with an integer or a number with terminal or repeating decimals (like 1.333333), then your number is rational! In other words, most numbers are rational numbers. This equation shows that all integers, finite decimals, and repeating decimals are rational numbers. The denominator in a rational number cannot be zero.Įxpressed as an equation, a rational number is a number Okay! Now that we know those terms, let’s turn to our original question.Ī rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. Fractions also have denominators, which are the numbers on the bottom of the fraction that show how many parts are in the whole.Fractions have numerators, which are the numbers on the top of the fraction that show the parts taken from the whole.Fractions are numbers that are expressed as ratios.Integers are whole numbers (like 1, 2, 3, and 4) and their negative counterparts (like -1, -2, -3, and -4).In order to understand what rational numbers are, we first need to cover some basic math definitions: In this article, we’ll discuss the rational number definition, give rational numbers examples, and offer some tips and tricks for understanding if a number is rational or irrational. Have you heard the term “rational numbers?” Are you wondering, “What is a rational number?” If so, you’re in the right place!
