What are the rules in multiplying rational numbers?
Rational numbers are numbers that can be written as the fraction of two integers. To multiply rational numbers together, you multiply the tops and bottoms separately to get your answer.
What happens when you multiply a positive by a negative?
When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12.
What is positive and negative rational number with example?
Examples of positive rational numbers are 3/8, 9/10, -34/-40, etc. On the other hand, there are negative rational numbers that have opposite signs in numerator and denominator, such as -4/15, 5/-6, -17/19, etc.

How do we multiply rational expression?
The method of multiplying rational expressions is same as the method of multiplying fractions . That is, just multiply the numerators to get the numerator of the product and multiply the denominators to get the denominator of the product. For all rational expressions ab and cd with b≠0 and d≠0 , ab⋅cd=acbd .
