Multiplication of Rational Numbers
Multiplication of Rational Numbers:
The product of two given fractions is a fraction whose numerator is the product of the numerators of the given fractions and whose denominator is the product of the denominators of the given fractions.
In other words, product of two given fractions = product of their numerators/product of their denominators
Similarly, we will follow the same rule for the product of rational numbers.
Therefore, product of two rational numbers = product of their numerators/product of their denominators.
Thus, if a/b and c/d are any two rational numbers, then
a/b × c/d = a × c/b × d
Example: Multiply 2/7 by 3/5
Solution:
2/7 × 3/5
= (2 × 3)/(7 × 5)
= 6/35
Example: Multiply 5/9 by (-3/4)
Solution:
5/9 × (-3/4)
= 5 × -3/9 × 4
= -15/36
= -5/12
