Less than is used to describe the relationship between two values. It tells us that the given variable is either less than, greater than, or equal to. For example, if 1 < 3 is given, it means that 1 is less than 3. Let us learn how to identify if the number is less than along with the importance of less than symbol and how to use it in detail.

What is Less Than?
Less than indicates that one value is lesser than the other. It is a term used to show the comparison between two or more quantities. For example, if we want to show the comparison between 2 and 3 we will say it as 2 is less than 3 or 3 is greater than 2. Hence it depicts the relationship between these two numbers. We can show these numbers as 2 < 3.
Less Than Symbol
Look at the below symbol.
This sign is called the less than sign in math. This is used to show that one value is lesser than the other value. Let us try using it within an example. If the statement says "16 is less than 18" is true. Then, we can write it as 16 < 18 using the less-than sign. The wide-open side of the sign with its two points always faces the bigger number, whereas the smaller endpoint faces the smaller number.
When to Use Less Than?
Let's compare the two-digit numbers, 32 and 14. While comparing the two-digit numbers, we first compare the tens digits. If the tens digits are the same, we will compare the one's digits.
Here, we can see that 1 is less than 3. Thus, we can say that 14 is less than 32. Mathematically, we can write it as 14 < 32 using the less-than sign. Given below are few more examples showing the comparison between numbers using less than sign.
|Less than <||
a) 23 < 32
b) 52 < 78
c) 100 > 85
a) The number 23 is less than 32.
b) The number 52 is less than 78.
c) The number 85 is less than 100.
Use of Less than in Algebra
In mathematics, the less than and the greater than symbols describe the inequality between two values. The symbol “< “ is used to represent less than inequality.
Important notes on Less Than
- One of the easiest ways to remember the "greater than" and "less than" signs is to imagine them as hungry alligators that always eat the larger number. Hence, the wide-open side of the sign faces a larger number.
- Another way to memorize them is to observe that the sign "<" looks similar to the alphabet "L". In other words, "<" means "Less than."
Given below is the list of topics that are closely connected to the less than. These topics will also give you a glimpse of how such concepts are covered in Cuemath.
Less Than Examples
Example 1: Erica had to collect various kinds of leaves and paste them in 2 sheets. In order to place them all in two sheets, she pasted 8 on sheet-I and 9 on sheet-II. Which sheet has fewer leaves?
As a part of her assignment, Erica passed 8 leaves on Sheet-I and 9 on Sheet-II.
The number 8 is less than the number 9
Thus, sheet-I leaves are less than sheet-II leaves.
8 < 9
Sheet-I Leaves < Sheet-II Leaves
Example 2: A cow weighs 400 lbs. The weight of her calf is 350 lbs. Which of them weighs less? Use less than symbol to represent this information.
Weight of the cow = 400 lbs
Weight of the calf = 350 lbs
Let's observe the numbers, 400 and 350
They are three-digit numbers.
By comparing the digits, thus, the information is represented as 350 < 400.
FAQs on Less Than
What is Less Than in Math?
Less than as the name suggests, means something is lesser than in comparison to some other quantity. It is represented by the symbol "<". For example, 2 < 4 means the number 2 is less than the number 4.
What is the Symbol for Less Than or Equal To?
The symbol of "less than or equal to" looks like " < ". The open side of the symbol should be in front of a bigger value. The underline in the symbol shows that the value could be equal to or more than the limit. For example, x < 7.
Here, the value of x should either be equal to or less than 7.
How do you Explain Less Than or Equal To?
Less than or equal to is something either lesser than or equal to a given quantity. It can also be expressed as at least or minimum. For example, the basic salary of women should be $15 or less than $15 or we can say it should be less than or equal to $15.
What is the Difference Between Less Than and Greater Than?
The greater than means that some variable or number can have any value that is greater than the given limit, not less than that, or equal to that limit, whereas the less than states that the number or variable can be less than the given limit. For example, 8 is greater than 5. We can represent this in two different ways, such as 8 > 5 and 5 is less than 8 (5 < 8).
What is the Difference Between Greater Than or Equal To and Less Than or Equal To?
The greater than or equal to tells that the amount either should be more or equal to the minimum limit whereas the less than or equal to is just opposite of greater than and equal to. Less than or equal to means, the amount should be equal or less than the maximum limit.
Is 4 Less Than 3?
No, we can't say 4 is less than 3. Because 4 is bigger than 3. Therefore the correct sentence will be 4 is greater than 3.
What is the use of Less Than Sign?
Less than sign is used to show that one variable is lesser than a given quantity. For example, 75 is less than 85. This can be represented as 75<85.
Can Less Than be Represented on a Number Line?
Yes, less than can be represented on the number line. Representing numbers on a number line makes it easy to identify which numbers are greater or lesser. A number on the left is less than a number on the right. Hence, all the numbers which are on the left of 1 are less than 1.
What Number is Less Than a Negative Number?
On the number line, negative numbers are to the left of zero. The greatest negative integer is -1. There is no smallest negative integer.
