# CLASS-4RECIPROCAL OF FRACTION

RECIPROCAL FRACTIONS -

Two numbers are reciprocals of each other if their product is one.

RECIPROCAL OF A GIVEN FRACTION -

Numerator                    Denominator

----------------  will be  ----------------   (The Inverse)

Denominator                   Numerator

a)  The reciprocal of one is itself.

b)  Zero does not have any reciprocal.

There are some examples are given below for your better understanding -

11

Example.1)  --------

6

11

Ans.)   -------

6

Numerator (N)                      Denominator (D)

As we know that, ---------------- = Reciprocal = -----------------

Denominator (D)                       Numerator (N)

6

= -------    (Ans.)

11

5

Example.2)   7 -------

6

5           47

Ans.)  7 ------- = --------   (Converted to improper fractions)

6            6

Numerator (N)                       Denominator (D)

As we know that, ---------------- = Reciprocal = -----------------

Denominator (D)                       Numerator (N)

6

= -------    (Ans.)

47

Example.3)  9

9

Ans.)  Given number 9 in Fraction can be written as ------

1

Numerator (N)                       Denominator (D)

As we know that, ---------------- = Reciprocal = -----------------

Denominator (D)                       Numerator (N)

1

= -------    (Ans.)

9

There is some other way of understanding reciprocal of fraction -
