In order to teach students the concept of equivalence when working with fractions with unlike denominators or finding equivalent fractions‚ there are some skills that the students must already possess. These are as follows: Students are able to both recognize and write fractions Students understand the ‘breakdown’ of a fraction where the top is the numerator and the bottom is the denominator Students must have some understanding of equivalence and what it means Students must be able to both

Fraction (mathematics) A fraction (from Latin: fractus‚ "broken") represents a part of a whole or‚ more generally‚ any number of equal parts. When spoken in everyday English‚ a fraction describes how many parts of a certain size there are‚ for example‚ one-half‚ eight-fifths‚ three-quarters. A common‚ vulgar‚ or simple fraction (examples: \tfrac{1}{2} and 17/3) consists of an integer numerator‚ displayed above a line (or before a slash)‚ and a non-zero integer denominator‚ displayed below (or after)

In Lacsap’s Fractions‚ when looking for a general pattern for the numerator‚ it can be noted that it does not increase linearly but exponentially. Numerators are 3‚6‚10‚ and 15‚ each preceding numerator added by one plus the row number. Using this general statement it can be concluded that the numerator in the 6th row is 21 (15+6)‚ and 28 for the 7th. Generating a Statement for the Numerator: To generate an equation for the numerator of the fraction‚ the fraction data must be organized and

Mixed Fractions (Also called "Mixed Numbers") | | A Mixed Fraction is a whole number and a proper fraction combined. such as 1 3/4. | 1 3/4 | | | (one and three-quarters) | | | Examples 2 3/8 | 7 1/4 | 1 14/15 | 21 4/5 | See how each example is made up of a whole number and a proper fraction together? That is why it is called a "mixed" fraction (or mixed number). Names We can give names to every part of a mixed fraction: Three Types of Fractions There are three types

Basic Concepts on Fraction Fraction – is defined as a part of a whole. In some other books‚ it is defined as a number written in the form ab ‚ where “a” and “b” are numbers and “b” is not equal to zero. Basic Parts of a Fraction * Numerator – the number above tells how many parts are taken. * Denominator – the number below tells how many equal parts the whole is divided. * Fraction bar – line that separates the two numbers. It also indicates division. There are several kinds

What’s So Hard About Fractions? Fractions as we know them today‚ the symbols and the algorithms for performing operations‚ have developed over thousands of years‚ beginning with ancient Egyptians. Through research of the origins‚ the development of fractions to appearing symbolically as we know them today‚ and of the developments of how we operate with them today and then connecting that knowledge with the observations of contemporary math education experts and personal interviews and observation

we let x = the number of hours it takes them to paint the kitchen working together. Below is a table that relates the data from our problem. We are using the concept that (rate)(time) = fraction of the task done. Now we can write an equation to represent: Fraction of work done by Sue in x hours + Fraction of work done by Joe in x hours = 1 job completed For your initial response: Complete both parts. a) Solve the rational equation in the example above. Make sure you label your answer properly

several concepts about fractions. One concept students in fourth grade will need to master is learning how to tell if fractions are equivalent with unlike denominators. There are a few prerequisite skills that are necessary in order for the students to understand this concept. The first thing students need to know is what fractions are. Fractions are a way of counting parts of a whole. Secondly‚ the students need to know how to identify parts of a fraction. The top number in a fraction is the numerator

Fractions are ways to represent parts of a whole. Common fractions are ½ and ¾. These are proper or regular fractions. Some fractions are called mixed numbers. These are represented by a whole number with a fraction (proper fraction). 1 ½ and 2 ¾ are good examples. An improper fraction has a larger number on the top than on the bottom‚ such as 9/8. I will explain how to convert these fractions to decimals. I will show you how to change an improper fraction to a mixed number. Operations (addition
