Introduction of the Product of Fractions

In this article, we learn to find the product of fractions. Fractions are defined by a numerical value that represents a part of a whole. A fraction can be a portion or section of any quantity out of a whole, whereas the whole can be any number, a specific value, or a thing. When a fraction is multiplied by another fraction the resultant is also a fraction or a whole number and it's called the product of fractions. We are aware that a fraction has two main parts: a numerator and a denominator. In order to multiply any two fractions, we should multiply the numerators and denominators, respectively. Before finding the product of fractions, let’s discuss the types of fractions.

Product of fractions

Product of fractions

Fractions and Their Types

The fractions define the ratio of two numbers. If a fraction is represented as $\dfrac{a}{b}$, where ‘a’ is the numerator and ‘b’ is the denominator. The three main types of fractions are mixed, proper, and improper fractions.

Proper fractions

When a fraction's numerator is less than its denominator.

Example: $\dfrac{1}{2}$, $\dfrac{3}{4}$

Improper fractions

When a fraction's numerator is greater than its denominator.

Example: $\dfrac{3}{2}$, $\dfrac{5}{3}$

Mixed Fraction

A result that includes both a whole number and a fraction.

Examples: $3 \dfrac{1}{4}$, $4 \dfrac{1}{5}$

The Product of the Fractions

The product of the fractions is defined as the product of two or more fractions in the form of a fraction or the variables.

How to Find the Product of the Fractions?

The steps to find the product of the fractions:

Step1: Multiply the numerator with the numerator.

Step2: Multiply the denominator with the denominator.

Step3: Simplify the fractions.

Steps of finding the product of fractions

If “$\dfrac{a}{b}$” and “$\dfrac{c}{d}$” are the two fractions, then the formula for product of fractions is:

$\dfrac{a}{b} \times \dfrac{c}{d} = \dfrac{ac}{bd}$

Product of the Fraction = $\dfrac{\text{Product of the Numerators}}{\text{Product of the Denominators}}$


Q. Find the product of fractions $\dfrac{3}{2}$ and $\dfrac{4}{5}$.

Ans. The product of the given fractions is:

$\dfrac{3}{2} \times \dfrac{4}{5}$ = $\dfrac{12}{10}$

On simplification, we get $\dfrac{6}{5}$.

Therefore, the product of $\dfrac{3}{2}$ and $\dfrac{4}{5}$ is $\dfrac{6}{5}$.

How to Find the Product of Mixed Fractions?

When a fraction contains both a whole number and a proper fraction, it is called a mixed fraction. Steps are following:

Step 1: Make improper fractions from the mixed fractions.

Step 2: Multiply the Fractions.

Step 3: Convert the product back to Mixed Fractions.

Find the Product of Fractions with Whole Numbers

To find the product of fractions with whole numbers, we apply the rule of multiplying the numerators, then the denominators, and then reducing them to the simplest terms. Whole numbers are written in the fractional form by adding ‘1’ to the denominator. A fraction can be used to represent a whole number, like, $3=\dfrac{3}{1}$, in which 3 is the numerator and 1 as the denominator.

  • You can find the product of any fraction by a whole number simply by multiplying the numerator by the whole number.

Examples of the product of fractions with whole numbers

Examples of the product of fractions with whole numbers

Example1: Find the product of $\dfrac{4}{5} \times 6$.

Solution: Steps to find the product of fractions:

  • Step1: 6 is a whole number, it may be expressed as $\dfrac{6}{1}$.

  • Step2: This means, $\dfrac{4}{5} \times \dfrac{6}{1}$.

  • Step3: Multiply the numerators, $4 \times 6 = 24$.

  • Step4: Multiply the denominators, $5 \times 1 = 5$.

  • Step5: The result is $\dfrac{24}{5}$ which cannot be further reduced.

Example2: Find the product of the fraction $4 \times \dfrac{5}{12}$ or find the fraction.

Solution: Multiply the numerators, $4 \times 5 = 20$.

The denominator stays the same.

$4 \times \dfrac{5}{12} = \dfrac{20}{12}$.

To simplify this fraction, both 20 and 12 are divisible by 4.

$4 \times \dfrac{5}{12} = \dfrac{20}{12} = \dfrac{5}{3}$

It cannot be divided further.

Find the Product of the Mixed Fractions

To find the product of the mixed fractions, before multiplication, we must convert the mixed fractions into improper fractions. For example, if the fraction is $3 \dfrac{2}{3}$, we should change it to $\dfrac{11}{3}$.

Example: Find the product of $2 \dfrac{2}{3}$ and $2 \dfrac{3}{4}$.

Ans: The following steps used to find the product of the mixed fractions.

Step1: Convert the mixed fractions to improper fractions, i.e., $2 \dfrac{2}{3} = \dfrac{8}{3}$ and $2 \dfrac{3}{4} = \dfrac{11}{4}$.

We get $\dfrac{8}{3} \times \dfrac{11}{4}$

Step2: Now multiply the numerators, and then multiply the denominators. We get $\dfrac{88}{12}$.

Step3: Now, reduce the resulting fraction by the lowest possible number of terms, then we get $\dfrac{22}{3}$.

Step4: Finally, change the result back to a mixed fraction, i.e., $7 \dfrac{1}{3}$.

Find the Product of the Fractions Calculator

A free online calculator tool is used to get the product of the fractions called the multiply fractions calculator. The steps that followed to use the calculator for multiplying fractions:

Step1: Type the fractions into the appropriate input field.

Step2: Now to obtain the product, click the "Multiply" button.

Step3: Finally, the output field will show the result of two fractions.

In this article, we got to know about finding the product of fractions. Here we specifically learned to find the product of fractions with whole numbers and the product of mixed fractions with different methods. To find the product of fractions, first, simply reduce the fraction to its lowest term. The product of fractions is always obtained in $\dfrac{a}{b}$ form.

FAQs on Find the Product of Fractions

1. Is multiplying and dividing fractions similar?

When two fractions are divided, the first fraction is multiplied by the second fraction's inverse. The first step for dividing fractions, reversing their numerator and denominator to find the inverse of the second fraction. After that, we multiply the two fractions.

2. Do we need common denominators to multiply fractions?

No, multiplying fractions does not require a common denominator. Any two fractions that have numerators that are multiplied by one another and denominators that are multiplied by one another can be multiplied.

3. What is the product of a fraction and zero?
