“A part of collection”
IMPROPER FRACTION
Number of Consider Parts
Fraction = When numerator is greater than denominator
Number of Total Parts 7 6 8
e.g. , ,
5 2 7
MIXED FRACTION
Combination of whole number + Proper fraction
Mixed Fraction to Improper Fraction e.g. 3 1 = 3 + 1
(Whole Number × Denominator) 5 5
+ Numerator 6 1 = 6 + 1
Mixed Fraction = Denominator 9 9
UNIT FRACTION
= Improper Fraction
Proper fraction with ‘1’ numerator
1 1 1
e.g. , ,
11 7 10
Improper Fraction to Mixed Fraction LIKE FRACTIONS
Remainder Fractions with same denominator
Improper Fraction = Quotient
Divisor e.g. 1 , 4 , 7 11
,
5 5 5 5
UNLIKE FRACTIONS
Fractions with different denominators
1 2 6

1. If two fractions have the same denominator, EQUIVALENT FRACTIONS
then larger the numerator, larger the fraction.
2. If two fractions have the same numerator, then These fractions which have same value
larger the denominator, smaller the fraction. e.g. 1 , 2 , 4
4
8
2
3. The reciprocal of 1 is 1 itself. all are equivalent fractions
