Key Concepts Fractions Pdf To justify why two rational numbers may be collected together, or added together, only if they have the same denominators, we visualize a fraction geometrically as a piece of a pie which is divided into equal unit parts. In this unit we shall look at the basic concept of fractions — what they are, what they look like, why we have them and how we use them. we shall also look at different ways of writing down the same fraction.
Fractions Pdf Abstract Algebra Mathematical Objects About the study aving together ideas of division, proportion, and equivalence. from elementary arithmetic to advanced algebraic structures, fractions play a ubiquitous role in mathematical discourse. This book was developed as a workbook and reference useful to students, teachers, parents, or anyone else who needs to review or improve their understanding of the mathematical concept of fractions. The top part of a fraction is called the numerator, while the bottom part of a fraction is called the denominator. the denominator states how many total parts the whole has been divided into. They learn to represent fractions with fraction strips (made of paper or just draw ings), fraction bars, rectangles, number lines, and other manipulatives.

They learn to represent fractions with fraction strips (made of paper or just draw ings), fraction bars, rectangles, number lines, and other manipulatives. When we build fractions to represent a situation, the numerator is what we want to talk about and the denominator is how much the total is. in a class of 7 students, 3 are wearing blue shirts. There are two ways of thinking about fractions: in terms of size or in terms of sets. an example of when size matters with fraction is if you have a cake; you divide the whole cake up into equal size pieces. Since 12 is a multiple that the denominators share in common, multiply the numerator and denominator of each fraction by an appropriate missing factor in the form of the “big 1” so that the resulting denominator is 12. In summary • seeing fractions as a set of interrelated concepts encompassing both dividing and measuring may help students to understand them • considering fractions as abstract and composite ideas can help extend students’ understanding from natural numbers to real numbers.
