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
