Introduction to Multiplication of Fractions
The multiplication of fractions is not like the addition or subtraction of fractions, where the denominator should be the same. Here, any two fractions with different denominators can easily be multiplied. The only thing to be kept in mind is that the fractions should not be in the mixed form, they should either be proper fractions or improper fractions. Let us learn how to multiply fractions through the following steps:
 Multiply the numerators.
 Multiply the denominators.
 Reduce the resultant fraction to its lowest terms.
For example, let's multiply the following fractions: 2/3 × 4/5. We start by multiplying the numerators: 2 × 4 = 8, then, the denominators: 3 × 5 = 15. This can be written as: (2 × 4)/(3 × 5) = 8/15. Now, the product is already in its lowest terms, so we need not reduce it and we give this as the answer.
Visual Representation of Multiplication of Fractions
Now, let us see the visual representation for the multiplication of fractions. Visualizing multiplication of fractions using fractional squares is a very interesting method to understand the concept. Do you know what are fractional squares? Fractional squares are a representation of the given fraction in the form of squares where the numerator is indicated as the shaded portion. Let us see how to multiply a fraction using fractional squares. Let's multiply these two fractions: 2/3 × 1/2.
In the above figure, the fractional square on the left has 2 orangeshaded parts out of 3 equal sections. This orange area represents twothirds of the fractional square. Similarly, the second shaded area represents half of the fraction square. By multiplying these two fraction squares, we get 2/6. This can be reduced to its simplest form and represented by one part of three squares. Thus, 2/3 × 1/2 = 2/6 = 1/3. Now that you have the insight into multiplying fractions, let us explore this topic further.
Multiplication of Fractions
Multiplication of Fractions with Whole Numbers: Multiplying fractions by whole numbers is an easy concept. Let us consider this example: 4 × 2/3. We will first represent this example using fractional squares. Four times twothirds is represented as:
Now let us change the improper fraction obtained into a mixed fraction. 8/3 = \(2\frac{2}{3}\). Two whole and two thirds which is equal to 8/3. Finally, we get the following representation.
Multiplication of Proper Fractions: Multiplication of proper fractions is the easiest of all. For example, let us take 2/3 × 4/6. Here, 2/3 and 4/6 are proper fractions. To multiply them, we will take the following steps:
 We will multiply the numerators together: 2 × 4 = 8.
 Then multiply the denominators together: 3 × 6 = 18. This can also be written as: (2 × 4)/(3 × 6) = 8/18.
 Then, reduce the resultant fraction to its lowest terms which will be 4/9.
Multiplication of Improper Fractions: Now let us understand the multiplication of improper fractions. We already know that an improper fraction is one where the numerator is bigger than the denominator. When multiplying two improper fractions, we frequently end up with an improper fraction. For example, to multiply 3/2 × 7/5 which are two improper fractions, we need to take the following steps:
 Multiply the numerators and denominators.(3 × 7)/(2 × 5) = 21/10.
 The fraction 21/10 cannot be reduced further to its lowest terms.
 Hence, the answer is: 21/10 which can be written as \(2\frac{1}{10}\).
Multiplication of Mixed Fractions: Mixed fractions are fractions that have a whole number and a fraction, like \(2\frac{1}{2}\). When multiplying mixed fractions, we need to change the mixed fractions into an improper fraction before multiplying. For example, if the number is \(2\frac{2}{3}\), you should change this to (3 × 2 + 2)/3 = 8/3. Let's consider an example. To multiply \(2\frac{2}{3}\) and \(3\frac{1}{4}\), the following steps can be used:
 Change the given mixed fractions to improper fraction. (8/3) × (13/4)
 Multiply the numerators of the improper fractions, and then multiply the denominators. This will give 104/12.
 Now, reduce the resultant fraction to its lowest terms, which will make it 26/3.
 Further, convert the answer back to mixed fraction which will be: \(8\frac{2}{3}\)
Observe that the above example shows how mixed fractions can be represented by fractional squares. The first two blocks show the whole number 2 and the third one represents the fraction 2/3. Now that we have seen the multiplication of fractions in various forms, let us revise the steps which explain how two given fractions are multiplied.The following figure shows the steps of multiplying two mixed fractions.
Important Notes:
Here are a few important notes which are helpful in the multiplication of fractions.
 Generally, students simplify a fraction after multiplication. However, to make calculations easier, check if the two fractions to be multiplied are already in their lowest forms. If not, first simplify them and then multiply. For example, \(\begin{align} \frac{4}{12}\times \frac{5}{13}\end{align}\) will be difficult to multiply directly.
 Now, if we simplify the fraction first, we get: \(\begin{align}\frac{1}{3}\times \frac{5}{13} = \frac{5}{39}\end{align}\).
 Simplification can also be done across two fractions. If there is a common factor between the numerator of one of the fractions and the denominator of the other fraction, you can simplify them and proceed. For example, \(\begin{align}\frac{5}{28}\times \frac{7}{9}\end{align}\) can be simplified to \(\begin{align}\frac{5}{4}\times \frac{1}{9}\end{align}\) before multiplying.
Solved Examples on Multiplication of Fractions

Example 1: Multiply the given fractions: 1/4 × 5/8
Solution:
To multiply the fractions 1/4 × 5/8, we start by multiplying the numerators: 1 × 5 = 5. After this, multiply the denominators: 4 × 8 = 32. This can be written as: (1 × 5)/(4 × 8) = 5/32. Now, this resultant fraction cannot be simplified further, so the answer is 5/32.

Example 2: Jishita's brother is \(1\frac{1}{2}\) meters tall. Jishita is \(1\frac{1}{5}\) times taller than her brother. How tall is Jishita?
Solution:
Jishita is \(\begin{align}1\frac{1}{5}\end{align}\) times \(\begin{align}1\frac{1}{2}\end{align}\) meters tall. The height of Jishita's brother is \(1\frac{1}{2}\) meters. Thus, Jishita's height will be \(1\frac{1}{2} \) × \(1\frac{1}{5}\) = 3/2 × 6/5 = ( 3 × 6)/(2 × 5) = 18/10 = 9/5 = \(1\frac{4}{5}\). Therefore, Jishita is \(1\frac{4}{5}\) meters tall.
