Number of Consider Parts 7 6 8
Fraction = e.g. , ,
Number of Total Parts 5 2 7
MIXED FRACTION
Combination of whole number + Proper fraction
1 1
Mixed Fraction to Improper Fraction e.g. 3 5 = 3 + 5
(Whole Number × Denominator) 1 1
+ Numerator 6 9 = 6 + 9
Mixed Fraction = Denominator
UNIT FRACTION
= Improper Fraction Proper fraction with ‘1’ numerator

1 1 1
e.g. , ,
11 7 10
LIKE FRACTIONS

Remainder e.g. 1 , 4 , 7 11
,
Improper Fraction = Quotient 5 5 5 5
Divisor
UNLIKE FRACTIONS
Fractions with different denominators
Rememberable Points 1 2 6
1. If two fractions have the same denominator, e.g. 3 , 5 , 7
then larger the numerator, larger the fraction. EQUIVALENT FRACTIONS
2. If two fractions have the same numerator, then Those fractions which have same value
large the denominator, smaller the fraction. 1 2 4
3. The reciprocal of 1 is 1 itself. e.g. 2 , 4 , 8
4. 0 does not have any reciprocal. all are equivalent fractions
