In this topic we will learn to add and subtract rational numbers with like, unlike and common denominators. Adding and subtracting rational numbers work exactly like fractions that you are already familiar with.
In this topic we will understand multiplication of fractions, like how to multiply a fraction with a whole number, how to multiply a fraction with a fraction, and how to multiply mixed numbers. We will use number line approach to understand this multiplication in a better way. Multiplying rational numbers works identical to how we multiply fractions which you are already familiar with.
