Lesson 10-Tenths and Hundredths- In this lesson, we will explore the concepts of tenths and hundredths. Tenths and hundredths are decimal fractions that represent parts of a whole.
- Tenths: Tenths are the first decimal place after the decimal point. They divide a whole into 10 equal parts. The denominator for tenths is always 10. The numerator represents the number of tenths.Example: In the number 0.5, the digit 5 is in the tenths place. So, we have 5 tenths or 0.5.Example: In the number 0.3, the digit 3 is also in the tenths place. So, we have 3 tenths or 0.3.
- Hundredths: Hundredths are the second decimal place after the decimal point. They divide a whole into 100 equal parts. The denominator for hundredths is always 100. The numerator represents the number of hundredths.Example: In the number 0.25, the digit 2 is in the tenths place, and the digit 5 is in the hundredths place. So, we have 25 hundredths or 0.25.Example: In the number 0.73, the digit 7 is in the tenths place, and the digit 3 is in the hundredths place. So, we have 73 hundredths or 0.73.
- Converting between tenths and hundredths: To convert tenths to hundredths, multiply the number of tenths by 10. To convert hundredths to tenths, divide the number of hundredths by 10.Example: 0.4 (4 tenths) can be written as 0.40 (40 hundredths). Example: 0.60 (60 hundredths) can be written as 0.6 (6 tenths).
- Comparing tenths and hundredths: When comparing tenths and hundredths, look at the digit in the highest decimal place. If the digits are the same, move to the next decimal place until a difference is found.Example: Compare 0.35 (3 tenths and 5 hundredths) and 0.36 (3 tenths and 6 hundredths). In this case, 0.36 is greater than 0.35 because the digit in the hundredths place (6) is greater than the digit in the hundredths place (5).
That’s it for this lesson on tenths and hundredths. Practice representing numbers in decimal form, converting between tenths and hundredths, and comparing decimal values.

Introduction: In this lesson, we will learn about tenths and hundredths, which are decimal fractions used to represent parts of a whole. We will explore how to read, write, compare, and convert numbers involving tenths and hundredths.
- Tenths:
- A tenth is one of the ten equal parts that a whole can be divided into.
- It is represented by the digit after the decimal point in decimal notation.
- For example, in the number 0.4, the digit 4 represents four tenths.
- Hundredths:
- A hundredth is one of the one hundred equal parts that a whole can be divided into.
- It is represented by the second digit after the decimal point in decimal notation.
- For example, in the number 0.27, the digit 7 represents seven hundredths.
- Reading and Writing Numbers with Tenths and Hundredths:
- To read a number with tenths and hundredths, say the whole number part followed by “and” and then state the tenths and hundredths.
- For example, 0.35 is read as “zero point three five” or “zero and thirty-five hundredths.”
- To write a number with tenths and hundredths, place the digits in the respective places after the decimal point.
- For example, the number three tenths and four hundredths is written as 0.34.
- Comparing and Ordering Numbers with Tenths and Hundredths:
- When comparing numbers with tenths and hundredths, start from the left and compare the digits one by one.
- If the digits in the highest decimal place are the same, move to the next decimal place until a difference is found.
- For example, 0.27 is greater than 0.21 because the digit in the tenths place (2) is greater than the digit in the tenths place (1).
- Converting between Tenths and Hundredths:
- To convert tenths to hundredths, multiply the number of tenths by 10.
- To convert hundredths to tenths, divide the number of hundredths by 10.
- For example, 0.5 (5 tenths) can be written as 0.50 (50 hundredths).
- For example, 0.80 (80 hundredths) can be written as 0.8 (8 tenths).
Conclusion: Understanding tenths and hundredths is essential for working with decimal numbers. Remember to represent them correctly, compare and order numbers involving these decimal places, and convert between tenths and hundredths as needed. Practice these skills to strengthen your understanding of decimal fractions.

Case Study on Class 5 Maths Lesson 10-Tenths and Hundredths
Using Tenths and Hundredths in Real-Life Situations
Let’s consider a case study where the concepts of tenths and hundredths from Class 5 Maths Lesson 10 are applied in a real-life scenario.
Case Study: Online Shopping
Sarah loves shopping online and recently ordered some items from an online store. Let’s see how she uses tenths and hundredths in various aspects of her online shopping experience.
- Pricing and Payments: Sarah is browsing through the website and comes across a pair of shoes she likes. The price of the shoes is listed as $39.99. Here, the digits after the decimal point represent the tenths and hundredths of a dollar. Sarah needs to pay $39 and 99 hundredths of a dollar for the shoes.
- Discounts and Savings: The online store is running a promotion offering a 20% discount on all items. Sarah applies the discount to the shoes she wants to purchase. The discounted price is calculated as 20% of $39.99, which is $7.998. Since Sarah can’t pay in fractions of cents, the store rounds it to the nearest cent, making the discounted price $7.99. Here, rounding is applied to the hundredths place.
- Tracking the Shipment: After placing her order, Sarah receives a confirmation email that includes a tracking number for her shipment. She can use the tracking number to track the progress of her package as it moves through different locations. The tracking system uses coordinates with tenths and hundredths to pinpoint the location of the package accurately.
- Delivery Time: The estimated delivery time for Sarah’s package is 3.5 days. The decimal value represents three whole days and five tenths of a day. This helps Sarah plan for the arrival of her package and anticipate when she can expect to receive it.
- Product Reviews and Ratings: Sarah likes to read product reviews before making a purchase. She notices that a particular item has an average rating of 4.7 out of 5. The decimal value in the rating represents the average satisfaction level, with the tenths place indicating a higher level of satisfaction. This helps Sarah gauge the quality and popularity of the product.
By understanding and applying the concepts of tenths and hundredths, Sarah successfully navigates her online shopping experience. She uses decimal fractions to understand pricing, discounts, track her shipment, estimate delivery time, and evaluate product reviews. These real-life applications demonstrate the practical relevance of the Class 5 Maths Lesson 10 on Tenths and Hundredths in everyday scenarios.
