The system grouped fractions in 10s and used two symbols, one for unit and another for 10.īelow are the symbols representing the Babylonian numeral system from numbers 1-20: But for calculations like angles and minutes for time, we also use base 60. Today, we usually organize numbers in groups of 10. BabyloniansĪnother civilization that created an elaborate system forįractions were the Babylonians, according to mathematics instructor and author Liz Pumfrey.īabylonians organized fractions in groups of 60 (base 60). To resolve the problem, Egyptians created extensive table listings that supplied the double values of various parts. However, the system did not allow unit fractions to be repeated in this sequence, making it difficult to do calculations. Parts were expressed as sums of unit fractions. Here are a few examples from Math Through the Ages: Egyptians marked the denominator with an oval or dot on top of the value. Since the numerator is always 1, they only had to indicate the denominator. Hieroglyphs represented their numbers, which means symbols corresponded to Idea, which is similar to number systems we use today. Unit fractions use 1 as its numerator.Įgyptian mathematicians created a system with a base 10 Their concept was mainly limited to parts, otherwise known as unit fractions. EgyptiansĪccording to Math Through the Ages : A Gentle History for Teachers and Others, the Egyptians were one of the first to devise a form of fraction as early as 1800 B.C. But different civilizations have their own way of standardizing fractions for universal use. The concept of fractions has been around for more than 4,000 years. Which means ‘breaking.’ In early English, it suggests a ‘broken off piece orįragment.’ The English word ‘fracture’ also Word Origin: The term fraction comes from the Latin 4 represents how many total parts are in a whole number, which is called the denominator.1 represents one slice or part of the whole number, which is called the numerator.In this case, it’s 1/4 of the entire cake. If you slice the cake into 4 equal parts, one slice is a fraction of that cake. To illustrate, think of a whole number like a cake. To describe how the parts relate with the whole number. Represent parts of a whole number, or any number of equal parts. In this section, we’ll talk about the origin of fractions, its importance in how information is delivered, and the golden ratio. Whether you get quarters for a change, buy outfits at 75% off, or cook with half a cup of butter, you’re using fractions. We practically deal with fractions every day. Multiply the fractions together (just like in the multiplication section above).įractions: History, Relevance, and Popular Uses.Turn the second fraction upside down to create the reciprocal number.
Add the second numerator from the first.Reduce result to most simplified number.Multiply each numerator by the same numbers the denominators were multiplied by.Find the lowest common denominator by multiplying each denominator by the other.
