Division of Rational Numbers
Division of Rational Numbers:
Divisions of rational numbers are similar to the divisions of fractions. To find the quotient of rational numbers, we need to recollect the concept of reciprocal of a rational number. Reciprocal of a rational number is nothing but the swapping of the numerator and denominator of that rational number i.e. invert the given the rational number will give you the reciprocal of that rational number. For example, 7/6 is the reciprocal of 6/7 . The product of a number and its reciprocal will always be 1.
In order to divide rational number, first change the division sign to . Then take the reciprocal of the number after the sign and multiply.
Example 5: Divide 11/12 and 7/4
Solution: To evaluate 11/12÷7/4
