3 <p>In mathematics, if one number is smaller than another, we use the symbol “<” to describe their relationship. For example, two friends received their scorecards, and one child scored 25 marks, which is less than another student’s score of 30. In this topic, we will learn about the less than sign and its importance.</p>

7 <p>We compare<a>numbers</a>to understand which is greater, smaller, or equal. In mathematics, the less than (<)<a>symbol</a>is used to show which number or quantity is smaller than the other. The “<” symbol explains that the value on the left side of the sign is smaller than the value on the right side.</p>

8 <p>For example, 4 < 5 means that 4 is less than 5. Since it compares two numbers or quantities, the less than symbol is known as a binary operator because it compares two values. The other common comparison symbols are<a>greater than</a>(>) and equal to (=).</p>

9 <h2>Comparison Symbols - Less Than, Greater Than, and Equal to</h2>

10 <p>In mathematics, we use three main symbols to compare numbers and quantities. By using these symbols, we can easily understand which one is smaller than, greater than, or equal to another.</p>

11 <strong>Features</strong><strong>Less than</strong><strong>Greater than</strong><strong>Equal to</strong>Symbol (<) (>) (=) Meaning The value on the left side is smaller than the value on the right. The value on the left side is greater than the value on the right. The values on both sides are equal. Example 3 < 6 9 > 7 3 = 3<h2>How to Use the Less Than Sign?</h2>

12 <p>Let’s learn how to use the less than sign by<a>comparing</a>two numbers: 34 and 18.</p>

13 <p>To begin, we have to identify the place values of the given numbers. When the given numbers have the same tens digit, move on to the ones digit.</p>

14 <p>Identify which number is less than the other and use the symbol “<”. When placing the symbol, make sure the pointed end faces the smaller number and the wide-open side of the sign faces the larger number. </p>

15 <p>Here, we can compare the tens digit of the given two numbers: 34 and 18. </p>

16 <p>As we know, 1 is smaller than 3. </p>

17 <p>Hence, 18 is less than 34. It can be written as 18 < 34. </p>

32 <p>The phrase “less than” means that the value on the left side is smaller than the value on the right side. It is written using the symbol “<”. When we reverse this symbol, it becomes “>”, which symbolizes the “greater than” symbol in mathematics. “Greater than” means that the value on the left side is larger than the value on the right side and is the opposite of “less than.”</p>

55 <p>How much less is 30 cm than 56.7 cm?</p>

56 <p>Okay, lets begin</p>

57 <p>30 cm is 26.7 cm less than 56.7 cm</p>

58 <h3>Explanation</h3>

59 <p>Here, we have two numbers to compare. So, we need to find out how much less 30 cm is compared to 56.7 cm.</p>

60 <p>Since 30 cm is less than 56.7 cm, </p>

61 <p>We subtract the small value from the large value. 56.7 - 30 = 26.7</p>

62 <p>Hence, the answer is that 30 cm is 26.7 cm less than 56.7 cm.</p>

64 <h3>Problem 2</h3>

65 <p>Sam and Vincent have fruit baskets. Sam has 25 mangoes, while Vincent has 22 mangoes. Who has fewer mangoes?</p>

66 <p>Okay, lets begin</p>

67 <p>Vincent has fewer mangoes than Sam.</p>

68 <h3>Explanation</h3>

69 <p>Sam has 25 mangoes.</p>

70 <p> Vincent has 22 mangoes. </p>

71 <p>To know who has fewer mangoes, we need to compare the number of mangoes both of them have. </p>

72 <p>Compared to Sam, who has 25 mangoes, Vincent has 22. </p>

73 <p>22 is less than 25.</p>

74 <p> It can be written as:</p>

75 <p> 22 < 25. </p>

76 <p>Hence, Vincent has 22 mangoes, which is less than Sam’s 25 mangoes.</p>

78 <h3>Problem 3</h3>

79 <p>Mary read 45 pages of a book, while her brother read 50 pages. Who read fewer pages?</p>

80 <p>Okay, lets begin</p>

81 <p>Mary read fewer pages than her brother.</p>

82 <h3>Explanation</h3>

83 <p>Mary read = 45 pages</p>

84 <p>Brother read = 50 pages </p>

85 <p>To find out who reads fewer pages, we compare both the numbers. </p>

86 <p>Since 45 is less than 50, Mary read fewer pages than her brother.</p>

87 <p>Well explained 👍</p>

88 <h3>Problem 4</h3>

89 <p>Tinto and Roy love candies. Tinto has 40 candies, while Roy has 35 candies. Who has fewer candies?</p>

90 <p>Okay, lets begin</p>

91 <p>Roy has fewer candies.</p>

92 <h3>Explanation</h3>

93 <p>First, we can start listing the number of candies each of them has.</p>

94 <p>Tinto = 40 candies</p>

95 <p> Roy = 35 candies</p>

96 <p> Now, compare the two numbers: 35 < 40</p>

97 <p>Hence, Roy has fewer candies than Tinto because 35 is less than 40.</p>

98 <p>Well explained 👍</p>

99 <h3>Problem 5</h3>

100 <p>In CMS School, there are two sections: Fiction and Non-Fiction. The Fiction section has 150 books, and the Non-Fiction section has 85 books. Which section has fewer books?</p>

101 <p>Okay, lets begin</p>

102 <p>The non-fiction section has fewer books</p>

103 <h3>Explanation</h3>

104 <p>To find out which section has fewer books, first identify how many books are in each section.</p>

105 <p>Fiction section = 150 books </p>

106 <p>Non-fiction section = 85 books </p>

107 <p>Now, we can compare the two numbers: </p>

108 <p> 85 < 150 </p>

109 <p>This shows that 85 is less than 150, so the non-fiction section has fewer books in CMS School.</p>

111 <h2>FAQs on Less Than</h2>

112 <h3>1.How to explain "Less than" to my child?</h3>

113 <p>In mathematics, less than is a comparison used to describe that one number or value is less than the other. The symbol “<” is used to represent the comparison of two numbers.</p>

114 <p>For example, give your child 4 cookies and tell them you have 6. Now count each cookies, and explain they have less cookies than you, since 4 < 6.</p>

115 <h3>2.How to explain difference between “less than” and “greater than” to my child?</h3>

116 <p>Explain to your child that we use comparison operators such as less than and greater than to compare quantities. Less than (<) means that the number on the left side of the sign is less than the one on the right side. Greater than (>) means that the number on the left side is greater than the number on the right side.</p>

117 <p>For example, 4 < 8 means 4 is smaller than 8. 10 > 7 means 10 is greater than 7.</p>

118 <h3>3.How do I explain to my child that negative numbers are less than zero?</h3>

119 <p>Give you child $2 and ask them to give you $3. Explain to them that since they have only given $2, they can't pay $3. So, they owe you $1. Now, the<a>money</a>they have is -$1. </p>

120 <h3>4.Are “less than” and “less than or equal to” the same?</h3>

121 <p>No, “less than” and ‘less than or equal to” are different concepts. If the number on the left side of the “less than” sign is smaller than the one on the right side, we use the symbol “<” to represent it. On the other hand, if the number on the left side can be smaller or equal to the number on the right side, it is represented by the “less than or equal to” (≤) symbol. </p>

122 <p>For example, if you have 1 flower and you child has 3, then you have less flowers than your child. Since, 1 < 3 (1 is less than 3). But if both of you have 5 flowers, then 5 ≤ 5 (5 is less than or equal to 5).</p>

123 <h3>5.How can I explain to my child that 5 is less than 3?</h3>

124 <p>Give me your child 3 toys and take 5 yourself. Ask them to count the each toys. After counting ask them who has more toys. </p>
