Basic Concept on Fractions
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 of fraction and they are grouped into two: INDIVIDUAL FRACTIONS and GROUP FRACTIONS Individual Fractions are taken as one. They are—
1. Proper Fraction - a fraction whose numerator is less than the denominator

Examples: 34 , 78 , 57

2. Improper Fraction - a fraction whose numerator is greater than or equal to the denominator.

Examples: 43 , 78 , 57

3. Mixed Fraction - combination of a whole number and a fraction.

Examples: 4 29 , 15 137 , 12 910
4. Unit Fraction - proper fraction whose numerator is always 1.
Examples: 111 , 16 , 15

Group Fraction – a fraction taken by group or set of fraction.
1. Similar Fraction - group or set of fraction with similar denominators. Examples: 612 , 812 , 912 , 412

2. Dissimilar Fraction - group or set of fraction with different denominators. Examples:

3. Equivalent Fraction - fractions which is equal in value. Examples: 23 = 812

Changing Improper Fraction to Mixed Number, to Whole Number, and Vice Versa
a. Improper Fraction to Mixed Fraction – divide the numerator by the denominator, the quotient will be the whole number and the divisor will be the denominator. 2

    Integers are the natural numbers of (0, 1,2,3,4….)and the negative non zero numbers of (-1,-2,-3,-4….)and so forth. Integers are numbers without a fractional or decimal component. Example: 23, 5, and -567 are integers, 8.45, 5½, and √2 are not integers. Integers are any number that can be expressed as the ratio of two integers. All integers are rational because integers can be expressed as a ratio of itself (9= 9/1) Rational numbers (fractional numbers) are regarded as divisions of integers. All numbers that are written as non-repeating, non-terminating decimals are “irrational” Example: Sqrt(2) or PI “3.14159…” the rational and irrationals are two different number types. Real numbers include whole numbers, rational numbers, and irrational numbers. A real number can be positive or negative or zero.…

    For example, 1/2, it is positive, so we move up 1, and to the right 2. If a fraction has a negative sign, then you move the fraction down in the negative direction a number of times based on the numerator, and to the right a number of times to the right based on the denominator. For example, -1/2 is negative, so we move down 1 and to the right 2 from our starting point.”…

    Equivalant Fractions with Unlike Denominators

    In elementary math there are 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. The numerator is the number of parts in a whole (Eather). The bottom number in a fraction is the denominator. The denominator is the number of parts the whole is divided into (Eather). Lastly, the student will need to have a basic knowledge of their multiplication and division facts. This will help the students in deciding whether or not the fraction is indeed equivalent or not.…

    How We Use Fractions Everyday

    If you walk down the aisles of your local mall you probably would get a third of the way there without coming in contact into a fraction in some way. After all, that walk down the aisle is a fraction: 1/3. Yes, we use fractions in one way or another in everyday life even though we may not completely realize it. For example, you use fractions every time you look at a clock. Yes, we know that quart past (1/4), half past (1/2) and quarter till (� 's past) are fractions. In fact, all time telling is a fraction of x/60 with the exception of when it is time on the hour as it then becomes a whole number (60/60 = 1) For example, 36 minutes past the hour is 3/5 's.This concept of looking at a clock is applicable to everything. Any value of anything that is not a whole number is a fraction! After all, that is what a fraction is�.a part of a whole. And there are parts of a whole everywhere! If you don 't believe this, then try baking a cake without using fractions. If it were not for fractions something as simple as baking a cake would be impossible. When you put 2 eggs into the cake mix you are using 1/6 of a dozen. In fact, every ingredient in a cake recipe is a fraction of something: a cup of milk, a teaspoon of salt, a stick of butter, a half a cup of chocolate chips. Can you imagine the result of baking a cake mixing an entire salt shaker, a gallon of milk, a pound of butter, a dozen eggs and an entire bag of chocolate chips? You would either have a really poor tasting cake or you would have a cake the size of the refrigerator! It is interesting to note that even those students who do very well on tests that feature fractions seem to very poorly on understanding how fractions work in everyday life. This is not because they do not grasp the concept of fractions but because they are somewhat disconnected between the way fractions make the transition from the classroom and into practical…
