Select The Best Answer For The Question.Which Of The Following Is An Example Of A Proper Fraction?A. \[$\frac{4}{3}\$\]B. \[$\frac{7}{6}\$\]C. \[$\frac{4}{4}\$\]D. \[$\frac{3}{4}\$\]
What are Fractions?
Fractions are a way to represent a part of a whole. They consist of two numbers: a numerator (the top number) and a denominator (the bottom number). The numerator tells us how many equal parts we have, while the denominator tells us how many parts the whole is divided into.
What is a Proper Fraction?
A proper fraction is a fraction where the numerator is less than the denominator. In other words, it is a fraction that is less than 1. Proper fractions are often used to represent a part of a whole that is less than the entire whole.
Examples of Proper Fractions
Let's take a look at the options provided:
- A. : This fraction has a numerator of 4 and a denominator of 3. Since 4 is not less than 3, this is not a proper fraction.
- B. : This fraction has a numerator of 7 and a denominator of 6. Since 7 is not less than 6, this is not a proper fraction.
- C. : This fraction has a numerator of 4 and a denominator of 4. Since 4 is equal to 4, this is not a proper fraction.
- D. : This fraction has a numerator of 3 and a denominator of 4. Since 3 is less than 4, this is a proper fraction.
Why is a Proper Fraction?
is a proper fraction because the numerator (3) is less than the denominator (4). This means that represents a part of a whole that is less than the entire whole.
Real-World Applications of Proper Fractions
Proper fractions are used in many real-world applications, such as:
- Cooking: When a recipe calls for a fraction of an ingredient, it is often a proper fraction. For example, a recipe might call for cup of sugar.
- Building: When building a structure, architects and engineers often use proper fractions to represent the proportions of different parts of the building.
- Science: In scientific experiments, proper fractions are often used to represent the proportions of different substances.
Conclusion
In conclusion, a proper fraction is a fraction where the numerator is less than the denominator. The example of a proper fraction from the options provided is . Proper fractions are used in many real-world applications, such as cooking, building, and science.

Final Thoughts
Q: What is a proper fraction?
A: A proper fraction is a fraction where the numerator is less than the denominator. In other words, it is a fraction that is less than 1.
Q: How do I identify a proper fraction?
A: To identify a proper fraction, simply compare the numerator and the denominator. If the numerator is less than the denominator, then it is a proper fraction.
Q: What is an example of a proper fraction?
A: An example of a proper fraction is . In this fraction, the numerator (3) is less than the denominator (4), making it a proper fraction.
Q: Can a proper fraction have a numerator equal to the denominator?
A: No, a proper fraction cannot have a numerator equal to the denominator. If the numerator is equal to the denominator, then the fraction is equal to 1, not less than 1.
Q: Can a proper fraction have a numerator greater than the denominator?
A: No, a proper fraction cannot have a numerator greater than the denominator. If the numerator is greater than the denominator, then the fraction is greater than 1, not less than 1.
Q: Why are proper fractions important?
A: Proper fractions are important because they are used in many real-world applications, such as cooking, building, and science. They help us to represent parts of a whole in a precise and accurate way.
Q: Can I use a calculator to simplify a proper fraction?
A: Yes, you can use a calculator to simplify a proper fraction. However, it's also important to understand the concept of simplifying fractions on your own, without relying on a calculator.
Q: How do I simplify a proper fraction?
A: To simplify a proper fraction, you can divide both the numerator and the denominator by their greatest common divisor (GCD). This will give you a simplified fraction that is equivalent to the original fraction.
Q: What is the greatest common divisor (GCD)?
A: The greatest common divisor (GCD) of two numbers is the largest number that divides both numbers without leaving a remainder.
Q: Can I add or subtract proper fractions?
A: Yes, you can add or subtract proper fractions, but only if they have the same denominator. If the fractions have different denominators, you will need to find a common denominator before you can add or subtract them.
Q: Can I multiply or divide proper fractions?
A: Yes, you can multiply or divide proper fractions. When multiplying or dividing fractions, you can simply multiply or divide the numerators and denominators separately.
Q: What are some real-world applications of proper fractions?
A: Some real-world applications of proper fractions include:
- Cooking: When a recipe calls for a fraction of an ingredient, it is often a proper fraction.
- Building: When building a structure, architects and engineers often use proper fractions to represent the proportions of different parts of the building.
- Science: In scientific experiments, proper fractions are often used to represent the proportions of different substances.
