Legend has it that the first person in ancient Greece who discovered that there are numbers that cannot be written as fractions was thrown overboard from a ship. Centuries later, while we regularly use numbers that cannot be written as fractions, those numbers that can be written as fractions remain powerful tools. What makes fractions so special? We explore how we can recognize the decimal representation of fractions and how fractions can be used to approximate any real number as closely as we wish.

Jun 28, 2015 · A fraction of two integers is a rational number. It is also a real number. Integers are the numbers: 0, 1, -1, 2, -2, 3, -3,.
A fraction of two integers is a rational number. It is also a real number. Integers are the numbers: 0, 1, -1, 2, -2, 3, -3,... Rational numbers are any number that can be expressed as p/q where p and q are integers and q != 0. So 5, 12.42, -17/3 and 0 are rational numbers. There are infinitely many rational numbers, but they do not form a continuous line. The continuous line of numbers is called the real number line. It includes all the previous numbers we have mentioned, but also numbers like sqrt(2), pi and e, which are not rational. Irrational numbers are any real numbers that are not rational.

FAQs
Are Fractions Real Numbers? ›
Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.
What is not a real number? ›A number which is imaginary, is NOT a real number. All real numbers can be expressed on the number line, while imaginary numbers cannot be expressed on the number line.
Is a fraction a real number an irrational number? ›Fractions are rational numbers so long as their bottom number (the denominator) is not zero, because dividing anything by zero is impossible.
Is every fraction a real number True or false? ›Every fraction is a rational number but vice versa is not true.
Are fractions and decimals real numbers? ›Real number: Real numbers are the set numbers that do not include any imaginary value. It includes all the positive integers, negative integers, fractions, and decimal values.
What qualifies as a real number? ›Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers.
What are 3 examples of non real numbers? ›Not all numbers are real numbers. The square root of a negative number is called a non-real or imaginary number. For example √−1, √−28 and √−5 are all non-real numbers.
Is a fraction never a irrational number? ›An irrational number is a real number that cannot be written as a ratio of two integers. In other words, it can't be written as a fraction where the numerator and denominator are both integers.
Can a fraction be a whole number? ›Fractions are not included in whole numbers but whole numbers can be written as fractions by representing it as a fraction with denominator as 1. Yes a fraction can be a whole number when it can be represented in the form of p/q with the value of q = 1.
Is a decimal a real number? ›Real numbers (R), (also called measuring numbers or measurement numbers). This includes all numbers that can be written as a decimal. This includes fractions written in decimal form e.g., 0.5, 0.75 2.35, ⁻0.073, 0.3333, or 2.142857.
Are integers and fractions real numbers? ›
Integers are a type of real number that just includes positive and negative whole numbers and natural numbers. Real numbers can include fractions due to rational and irrational numbers, but integers cannot include fractions.
Is A fraction a number? ›What is a fraction in Mathematics? A fraction is numerical value that is a part of a whole. It is evaluated by dividing a whole into number of parts. For example, ½ represents half of a whole number or a thing.
Why all fractions are not rational numbers? ›A fraction of two numbers represents a rational number if and only if it can be equal to a fraction of two integers. If the numerator and denominator are both rational, the number is rational. If one is rational and the other is irrational, the fraction is irrational. If they are both irrational you don't know.
Are all fractions rational numbers? ›All fractions can be termed as rational numbers; however, all rational numbers cannot be termed as fractions. Only those rational numbers in which 'p' and 'q' are positive integers are termed fractions. Let a/b be any fraction. Now, a and b are natural numbers.
What is a real number that is irrational? ›The real numbers which cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0 are known as irrational numbers. For example √2 and √ 3 etc. are irrational.
Are all real numbers irrational? ›Irrational numbers can also be expressed as non-terminating continued fractions and many other ways. As a consequence of Cantor's proof that the real numbers are uncountable and the rationals countable, it follows that almost all real numbers are irrational.
Is √ 27 a non real number? ›A non-real number: Similarly, i√27 is a non-real number because it has an imaginary component.
Is 1 not a real number? ›Mathematically, 1 is: in arithmetic (algebra) and calculus, the natural number that follows 0 and the multiplicative identity element of the integers, real numbers and complex numbers; more generally, in algebra, the multiplicative identity (also called unity), usually of a group or a ring.
Is negative 15 a real number? ›Real number: Real numbers are the set numbers that do not include any imaginary value. It includes all the positive integers, negative integers, fractions, and decimal values.
Is 0 a non real? ›The number 0 may or may not be considered a natural number, but it is an integer, and hence a rational number and a real number (as well as an algebraic number and a complex number). The number 0 is neither positive nor negative, and is usually displayed as the central number in a number line.
