The Relationship Between Tenths and Hundredths

Oct 13, 2025 by sorusgentrification.com 58 views

Introduction

In mathematics, decimals and mixed numbers are two essential ways to represent fractions. Decimals are numbers that have a fractional part, represented by a dot (.) followed by one or more digits. Mixed numbers, on the other hand, consist of a whole number part and a fractional part. In this article, we will explore the concept of decimal and mixed numbers, focusing on the relationship between tenths and hundredths.

The Relationship Between Tenths and Hundredths

As the title suggests, there are ten hundredths between any two numbers that are in tenths. This means that if we have two numbers in tenths, such as 0.5 and 0.6, there are ten hundredths between them, which can be represented as 0.50 and 0.60. This relationship is crucial in understanding decimals and mixed numbers.

Decimal and Mixed Numbers at Each Point

Let's examine the given values and points:

Point	Value (Decimal)	Value (Mixed Number)
J	5.40	5 2/5
K	5.45	5 9/20
L	5.50	5 1/2
M	5.55	5 11/20
N	5.60	5 2/5
O	5.65	5 13/20

Explanation of Each Point

J - 5.40

The decimal value 5.40 can be represented as a mixed number: 5 2/5. This means that 5.40 is equal to 5 whole units and 2/5 of a unit.

K - 5.45

The decimal value 5.45 can be represented as a mixed number: 5 9/20. This means that 5.45 is equal to 5 whole units and 9/20 of a unit.

L - 5.50

The decimal value 5.50 can be represented as a mixed number: 5 1/2. This means that 5.50 is equal to 5 whole units and 1/2 of a unit.

M - 5.55

The decimal value 5.55 can be represented as a mixed number: 5 11/20. This means that 5.55 is equal to 5 whole units and 11/20 of a unit.

N - 5.60

The decimal value 5.60 can be represented as a mixed number: 5 2/5. This means that 5.60 is equal to 5 whole units and 2/5 of a unit.

O - 5.65

The decimal value 5.65 can be represented as a mixed number: 5 13/20. This means that 5.65 is equal to 5 whole units and 13/20 of a unit.

Conclusion

In conclusion, understanding the relationship between tenths and hundredths is crucial in representing decimals and mixed numbers. By recognizing that there are ten hundredths between any two numbers that are in tenths, we can easily convert between decimals and mixed numbers. The examples provided in this article demonstrate how to represent decimal values as mixed numbers and vice versa.

Tips and Tricks

When converting a decimal to a mixed number, divide the fractional part by 10 to get the hundredths.
When converting a mixed number to a decimal, multiply the whole number part by 10 and add the fractional part.
Practice converting between decimals and mixed numbers to become more comfortable with the concept.

Real-World Applications

Understanding decimals and mixed numbers has numerous real-world applications, such as:

Cooking: Measuring ingredients in fractions of a unit, like 1/4 cup or 3/4 cup.
Building: Measuring lengths in fractions of a unit, like 1/2 inch or 3/4 inch.
Finance: Calculating interest rates and investments in fractions of a unit, like 1/4 percent or 3/4 percent.

Common Mistakes to Avoid

Confusing tenths and hundredths.
Not recognizing the relationship between tenths and hundredths.
Not practicing converting between decimals and mixed numbers.

Conclusion

Introduction

In our previous article, we explored the concept of decimals and mixed numbers, focusing on the relationship between tenths and hundredths. In this article, we will answer some frequently asked questions about decimals and mixed numbers to help you better understand this concept.

Q&A

Q: What is the difference between a decimal and a mixed number?

A: A decimal is a number that has a fractional part, represented by a dot (.) followed by one or more digits. A mixed number, on the other hand, consists of a whole number part and a fractional part.

Q: How do I convert a decimal to a mixed number?

A: To convert a decimal to a mixed number, divide the fractional part by 10 to get the hundredths. Then, write the whole number part and the fractional part as a mixed number.

Q: How do I convert a mixed number to a decimal?

A: To convert a mixed number to a decimal, multiply the whole number part by 10 and add the fractional part.

Q: What is the relationship between tenths and hundredths?

A: There are ten hundredths between any two numbers that are in tenths. This means that if we have two numbers in tenths, such as 0.5 and 0.6, there are ten hundredths between them, which can be represented as 0.50 and 0.60.

Q: How do I add or subtract decimals and mixed numbers?

A: When adding or subtracting decimals and mixed numbers, it's essential to line up the decimal points and the whole number parts. Then, add or subtract the fractional parts as you would with regular fractions.

Q: Can I simplify a mixed number?

A: Yes, you can simplify a mixed number by finding the greatest common divisor (GCD) of the whole number part and the fractional part. Then, divide both parts by the GCD to simplify the mixed number.

Q: How do I compare decimals and mixed numbers?

A: To compare decimals and mixed numbers, convert both numbers to a common form, such as a decimal or a mixed number. Then, compare the numbers as you would with regular fractions.

Q: What are some real-world applications of decimals and mixed numbers?

A: Decimals and mixed numbers have numerous real-world applications, such as:

Cooking: Measuring ingredients in fractions of a unit, like 1/4 cup or 3/4 cup.
Building: Measuring lengths in fractions of a unit, like 1/2 inch or 3/4 inch.
Finance: Calculating interest rates and investments in fractions of a unit, like 1/4 percent or 3/4 percent.
