What Are Fractions and Whole Numbers?
Before diving into the specifics of multiplying fractions with whole numbers, let’s start with a simple introduction to fractions and whole numbers.
Fractions are a mathematical way of expressing a value that is less than one. It represents a part of a whole. For instance, if you eat half of a pizza, you’ve eaten a fraction of the pizza. The fraction representing this is 1/2, where 1 is the numerator (part) and 2 is the denominator (whole).
On the other hand, whole numbers are simple, straightforward numbers that we use in our day-to-day life. They include all positive numbers, including zero, without any fractional or decimal components. Numbers like 0, 1, 2, 3, and so on are whole numbers.
Definition of Fractions
A fraction is a numerical quantity that represents a part of a whole. It consists of a numerator and a denominator. The numerator indicates how many parts we have, and the denominator indicates the total number of equal parts. For instance, in the fraction 3/4, 3 is the numerator and 4 is the denominator. Thus, it represents three parts out of a total of four.
Definition of Whole Numbers
Whole numbers are the set of numbers that include zero and all the natural numbers. They don’t contain any fractional or decimal part. They start from zero and go on indefinitely (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and so on).
Understanding the Concept of Multiplying Fractions with Whole Numbers
Multiplying fractions with whole numbers is not as complex as it may initially seem. In fact, the process is quite straightforward and logical. Essentially, you transform the whole number into a fraction by placing it over 1 and then multiply as you would with two fractions. We’ll explain this in more detail later in this article.
Properties of Fractions
Fractions have several key properties. For instance, any number over itself is equal to 1 (3/3 = 1). If the numerator is less than the denominator, the fraction is less than 1. And if the numerator is greater than the denominator, the fraction is greater than 1.
Properties of Whole Numbers
Whole numbers also have several key properties. They include closure (adding or multiplying two whole numbers always results in a whole number), associativity, commutativity, and the existence of an identity element (zero for addition and one for multiplication).
Properties of Multiplying Fractions with Whole Numbers
The properties of multiplying fractions with whole numbers are the same as multiplying two fractions. The result will still be a fraction, and you can simplify the fraction to its lowest term if possible.
Difference Between Fractions, Whole Numbers, and Their Multiplication
Fractions, whole numbers, and their multiplication have distinct differences. Fractions represent parts of a whole, while whole numbers are complete in themselves. When you multiply a fraction by a whole number, the result could either be another fraction, or it could be a whole number if the fraction multiplies to 1.
The Process of Multiplying Fractions with Whole Numbers
Multiplying fractions with whole numbers might seem a bit daunting at first, but it’s actually fairly simple. The first step is to convert the whole number into a fraction by placing it over 1. Then, multiply the numerators together to get the new numerator and the denominators together to get the new denominator.
Step-by-Step Guide on How to Multiply Fractions with Whole Numbers
Here’s a step-by-step guide on how to multiply fractions with whole numbers:
- Convert the whole number to a fraction by placing it over 1.
- Multiply the numerators together to get the new numerator.
- Multiply the denominators together to get the new denominator.
- Simplify the fraction to its lowest term, if possible.
Writing Equations of Multiplying Fractions with Whole Numbers
Let’s see how to write equations of multiplying fractions with whole numbers. Suppose we want to multiply the fraction 2/3 with the whole number 4. We first convert the whole number into a fraction (4/1), and then we multiply the numerators and denominators:
(2/3) x (4/1) = (2×4)/(3×1) = 8/3
Illustrating the Process with Numerical Equations
Let’s illustrate the process with numerical equations. Let’s multiply 3/4 with the whole number 5:
(3/4) x (5/1) = (3×5)/(4×1) = 15/4 = 3 3/4
In the last step, we’ve converted the improper fraction 15/4 into a mixed number 3 3/4 for easier understanding.
Practice Problems on Multiplying Fractions with Whole Numbers
Now, it’s time for some practice problems on multiplying fractions with whole numbers.
- Multiply 2/5 with the whole number 7.
- Multiply 3/8 with the whole number 3.
- Multiply 5/6 with the whole number 4.
Work on these problems, and check your answers by using the process we’ve explained.

Frequently Asked Questions on Multiplying Fractions with Whole Numbers
At Brighterly, we often receive questions on the topic of multiplying fractions with whole numbers. We’ve compiled a list of Frequently Asked Questions and provided detailed responses to support your learning journey.
What does it mean to multiply a fraction by a whole number?
Multiplying a fraction by a whole number means you are taking a part of the whole number. It involves converting the whole number to a fraction, multiplying the fractions, and simplifying if necessary.
How do you multiply fractions and whole numbers step-by-step?
First, convert the whole number to a fraction by placing it over 1. Next, multiply the numerators of the two fractions together for the new numerator, and do the same for the denominators. Finally, simplify the new fraction to its lowest terms if possible.
Why do we convert the whole number into a fraction for the multiplication?
Converting the whole number into a fraction makes the multiplication process consistent with the rule for multiplying fractions: multiply the numerators to get the new numerator and multiply the denominators to get the new denominator.
Can the result of multiplying a fraction and a whole number be a whole number?
Yes, the result can be a whole number. This happens when the fraction multiplied by the whole number equals 1 or another whole number.
Is multiplying a fraction by a whole number the same as multiplying a whole number by a fraction?
Yes, the order of multiplication does not change the result due to the commutative property of multiplication.
