In this lesson, we will learn what is the Reciprocal of a fraction, what is a Complex Fraction and how to simplify a Complex Fraction.
What is the Reciprocal of a fraction?
The reciprocal of a fraction is the fraction turned upside down. That is the numerator becomes the denominator and the denominator becomes the numerator, for example:
The reciprocal of
The reciprocal of or 8.
To get the reciprocal of a mixed number, first convert to improper fraction and then invert, for example:
The reciprocal of is Any number multiplied by its reciprocal will always be 1, for example:
What is a Complex Fraction? A complex fraction is a fraction within a fraction. If we have a fraction as the numerator, then the denominators are to be multiplied to get the simplified fraction.
If we have a fraction as the denominator, then the top numerator is multiplied with the reciprocal of the denominator to get the simplified fraction.
How to simplify a Complex Fraction?
Method 1 : Fraction Division
Method 2 : LCD Multiplication
