1.35 Division in Rational Numbers - I

Method:
To divide by a fraction, multiply by its reciprocal.
Example: 2 2/3 = 2 x 3/2 = 3

Definition: For any two rational numbers a/b and c/d, to divide a/b by c/d we multiply a/b with the multiplication inverse of c/d.

Therefore, a/b c/d = a/b d/c.

Example:
4/5 16/5 = ?
The multiplicative inverse of 16/5 is 5/16.
Therefore, the division of 4/5 16/5 = 4/5 5/16 = (4x5)/(5x16) = 20/80
