3 <p>Have you ever used money ₹10.50 or measured something as 2.5 cm? That’s a decimal. Decimals help us show whole numbers and fractions together. They are used in calculations, measurements, and money. Let’s learn more about them.</p>

4 <h2>What are Decimals in Math?</h2>

5 <p>What Are Numbers? 🔢 | Fun Explanation with 🎯 Real-Life Examples for Kids | ✨BrightCHAMPS Math</p>

6 <p>▶</p>

7 <p>Decimals are<a>numbers</a>that show both<a>whole numbers</a>and parts of a whole. They are written with a decimal point. For example, if a cake costs 5 dollars and 25 cents, we write it as $5.25 where 5 is the whole number and 25 is the fractional part. </p>

8 <p>Decimals are another way to write<a>fractions</a>. You can easily change a decimal to a fraction or a fraction to a decimal. For example, $\frac{3}{8}$ as a decimal is 0.375, and $\frac{1}{8}$ as a decimal is 0.125. Learning how to<a>convert decimals to fractions</a>helps in solving problems faster. </p>

9 <p>Decimals are used in daily life in<a>money</a>, measurements, and even in computers. In computers, we change binary to decimal or hexadecimal to decimal. Knowing<a>decimal place value</a>and decimal places helps us write and round numbers correctly. </p>

10 <p>There are two types of decimals<a>terminating decimals</a>(that end, like 0.5) and non-terminating decimals (that go on forever, like 0.333…). </p>

11 <p>You can also use a decimal calculator to change decimal to percent or percent to decimal easily. </p>

12 <p>Decimals have a long history. The idea of zero came from the Indian mathematician Aryabhata, which helped form modern decimals. Later, Simon Stevin and John Napier made decimals popular in math. </p>

13 <h2>Properties of Decimals</h2>

14 <p>Decimals are a<a>set</a>of numbers that express both whole numbers and fractional parts. They play a vital role in everyday calculations to scientific operations. Several properties that make decimals a convenient way to represent numbers are listed below: </p>

15 <ul><li><strong>Placing decimal in<a>multiplication</a>:</strong>When we add or<a>subtract decimals</a>, we should align the decimal points correctly. For example, 13.56 + 9.5 = 23.06. When<a>multiplying decimals</a>, we multiply them as whole numbers and then place the decimal point based on the total decimal places. For example, 3.5 × 1.4 = 4.9.</li>

16 <li><strong>Dividing decimals:</strong>To divide decimals, we shift the decimal point to make the<a>divisor</a>a whole number. For example, 4.0 ÷ 0.2 = 20. We can also use a decimal<a>calculator</a>for quick answers. Between two decimals like 0.1 and 0.2, there are more decimals, such as 0.15 and 0.17.</li>

17 <li><strong>Decimal fraction conversion:</strong>Decimals can be changed into fractions and vice versa. To convert a decimal to a fraction, write it over its<a>place value</a>; for example, 0.25 = $\frac{1}{4}$. To convert a fraction to a decimal, divide the numerator by the denominator; for example, $\frac{3}{8}$ as a decimal is 0.375 and $\frac{1}{8}$ as a decimal is 0.125.</li>

18 <li><strong>Decimal percent conversion:</strong>Decimals can also be written as percentages. To convert decimal to percent, multiply by 100 (0.75 = 75%), and to convert percent to decimal, divide by 100 (45% = 0.45). In computers, numbers are also written in binary, hex, and decimal forms. We can change binary to decimal or hexadecimal to decimal easily using conversion methods.</li>

19 <li><strong>Understanding terminating decimals:</strong>Some decimals stop after a few digits, they are called terminating decimals. For example, 1/4 = 0.25 is a terminating decimal.</li>

20 </ul><h2>Classification of Decimals</h2>

21 <p>Decimals are divided into three main types based on the numbers that appear after the decimal point: terminating decimals,<a>non-terminating decimals</a>, and recurring decimals. Understanding these categories helps us easily convert between<a>decimals and fractions</a>. </p>

22 <ul><li><strong>Terminating decimals</strong>Terminating decimals are those that stop after a few digits. They have a fixed number of decimal places, and<a>division</a>by them gives no<a>remainder</a>. For example, 0.25 is a<a>terminating decimal</a>because it ends after two digits. You can convert this decimal to a fraction as 0.25 = $\frac{25}{100}$ = $\frac{1}{4}$. Similarly, $\frac{1}{8}$ as a decimal is 0.125 and $\frac{3}{8}$ as a decimal is 0.375 both are terminating decimals. </li>

23 </ul><ul><li><strong>Non-Terminating decimals</strong>Non-terminating decimals go on endlessly after the decimal point. They have an infinite number of digits. Some of them follow a pattern, while others don’t. For example, 0.5555... continues forever, so it is a non-terminating decimal. When these decimals repeat, they are known as recurring decimals.</li>

24 <li><strong>Recurring decimals</strong>Recurring decimals are non-terminating decimals with repeating digits or groups of digits. For instance, 1.6777... repeats the digit 7 infinitely. These decimals can also be written as fractions. For example, $\frac{1}{3}$= 0.3333... and $\frac{1}{7}$ = 0.142857142857....</li>

111 <h2>FAQs on Decimals</h2>

112 <h3>1.What do you mean by decimal?</h3>

113 <p>Decimals are used to represent numbers that have both an integer part and also a fractional part. For example, 3.67 is a decimal number, where 3 is the integer part and 67 is the fractional part. A decimal point separates both parts. </p>

114 <h3>2. Explain terminating decimals.</h3>

115 <p>After the decimal point, terminating decimals have a finite number of digits. These digits end or terminate after a certain point, and they do not repeat. For instance, 0.34, 1.76, and 5.12 are some examples of terminating decimals. </p>

116 <h3>3.How do we find pure decimals?</h3>

117 <p>The value of pure decimals will be less than 1. Pure decimals refer to the decimals which have digits only after the decimal point. These decimals do not have a whole number, just the fractional part. For example, 0.4, 0.87, and 0.98 are the examples of pure decimals. </p>

118 <h3>4. What are the criteria for multiplying decimals?</h3>

119 <p>While multiplying decimals, overlook the decimal points and then multiply them as whole numbers. After multiplying, apply the decimal point to the final results by counting the decimal places of the given decimals. </p>

120 <h3>5. How to find the place value of decimals?</h3>

121 <p>In a decimal number, a decimal point divides the whole number and the fractional part. The value of numbers placed on the left side of the decimal point such as ones, tens, hundreds, and so on. The values of right-side numbers are tenths, hundredths, and so on. For example, in 1.35, 1 is in the ones place, 3 is in the tenths place, and 5 is in the hundredths place. </p>

122 <h3>6.How to pronounce decimal numbers?</h3>

123 <p>When we speak about a decimal number, the digits after the decimal point stand independently. For instance, 14.876 is a decimal number. Here, it is pronounced as fourteen point eight seven six. We do not count 876 as eight hundred and seventy-six. </p>

124 <h3>7.How can we round a decimal?</h3>

125 <p>If we want to round a decimal, look at the digits after the decimal points. If the last digit is 5 or<a>greater than</a>5, round up the digits on its left side. If the last digit is less than 5, round down. For example, 2. 458 can be rounded up to 2.46 </p>

126 <h3>8.Is 0.12 greater than 0.2?</h3>

127 <p>No, 0.2 is the greatest number. When we compare these decimals, 0.12 means 12 out of 100. Whereas, 0.2 means 20 out of 100. Hence, 0.2 is greater than 0.12. </p>

128 <h3>9.How do you define fractions and decimals?</h3>

129 <p>Decimals are used to represent whole numbers and fractions using<a>powers of 10</a>. While fractions are a part of a whole. It can be written as a<a>ratio</a>. For example, 3.56 is a decimal number whereas, ¼ is a fraction. </p>

130 <h3>10.What is the real-life significance of decimals?</h3>

131 <p>In our daily lives, decimals are commonly used to express precise results. When we are dealing with financial transactions, the amount is written in decimal form. Decimals are used to explain the weight and height of objects or anything else. The real-life applications of decimal numbers are numerous. </p>
