Introduction

In mathematics, we often encounter various operations involving whole numbers and fractions. One common operation is multiplication, where we multiply a whole number by a fraction. In this article, we will explore how the product of a whole number and a fraction compares to the whole number itself, using the example of $$7 \times \frac{5}{4}$$.

What is a Fraction?

A fraction is a way of expressing a part of a whole as a ratio of two numbers. It consists of a numerator (the top number) and a denominator (the bottom number). For example, in the fraction $$\frac{5}{4}$$, the numerator is 5 and the denominator is 4. The fraction $$\frac{5}{4}$$ represents five parts out of four equal parts.

Why is the Denominator Important?

When we multiply a whole number by a fraction, the denominator of the fraction plays a crucial role in determining the product. If the denominator is less than 1, the fraction is considered less than 1. Conversely, if the denominator is greater than 1, the fraction is considered greater than 1.

Comparing the Product to the Whole Number

Now, let's compare the product of $$7 \times \frac{5}{4}$$ to the whole number 7. To do this, we need to understand that when we multiply a whole number by a fraction, we are essentially multiplying the whole number by the numerator of the fraction and then dividing by the denominator.

The Calculation

To calculate the product of $$7 \times \frac{5}{4}$$, we multiply 7 by 5 and then divide by 4.

7 \times \frac{5}{4} = \frac{7 \times 5}{4} = \frac{35}{4}

Why the Product is Greater than the Whole Number

Now, let's compare the product $$\frac{35}{4}$$ to the whole number 7. Since the denominator of the fraction is 4, which is greater than 1, the fraction $$\frac{5}{4}$$ is considered greater than 1. When we multiply 7 by a fraction that is greater than 1, the product will be greater than the whole number itself.

Conclusion

In conclusion, the product of $$7 \times \frac{5}{4}$$ will be greater than the whole number 7 because we are multiplying 7 by a fraction that is greater than 1. This is due to the fact that the denominator of the fraction is 4, which is greater than 1. Therefore, the correct answer is:

A) It will be greater because we are multiplying 7 by a fraction that is greater than 1.

Example Problems

Here are a few example problems to help you understand the concept better:

$8 \times \frac{3}{2}$
$9 \times \frac{2}{3}$
$10 \times \frac{4}{5}$

Solutions

$8 \times \frac{3}{2} = \frac{8 \times 3}{2} = \frac{24}{2} = 12$
$9 \times \frac{2}{3} = \frac{9 \times 2}{3} = \frac{18}{3} = 6$
$10 \times \frac{4}{5} = \frac{10 \times 4}{5} = \frac{40}{5} = 8$

Practice Problems

Try solving the following practice problems to reinforce your understanding of the concept:

$6 \times \frac{7}{3}$
$4 \times \frac{9}{2}$
$3 \times \frac{8}{4}$

Answers

$6 \times \frac{7}{3} = \frac{6 \times 7}{3} = \frac{42}{3} = 14$
$4 \times \frac{9}{2} = \frac{4 \times 9}{2} = \frac{36}{2} = 18$
$3 \times \frac{8}{4} = \frac{3 \times 8}{4} = \frac{24}{4} = 6$

Conclusion

Q: What is the product of a whole number and a fraction?

A: The product of a whole number and a fraction is the result of multiplying the whole number by the numerator of the fraction and then dividing by the denominator.

Q: How do I calculate the product of a whole number and a fraction?

A: To calculate the product of a whole number and a fraction, you need to multiply the whole number by the numerator of the fraction and then divide by the denominator. For example, to calculate the product of 7 and $$\frac{5}{4}$$, you would multiply 7 by 5 and then divide by 4.

Q: Why is the denominator important when multiplying a whole number by a fraction?

A: The denominator is important because it determines the value of the fraction. If the denominator is less than 1, the fraction is considered less than 1. If the denominator is greater than 1, the fraction is considered greater than 1.

Q: What happens when the denominator is equal to 1?

A: When the denominator is equal to 1, the fraction is equal to the numerator. In this case, the product of the whole number and the fraction will be equal to the whole number itself.

Q: Can the product of a whole number and a fraction be less than the whole number?

A: Yes, the product of a whole number and a fraction can be less than the whole number if the fraction is less than 1.

Q: Can the product of a whole number and a fraction be greater than the whole number?

A: Yes, the product of a whole number and a fraction can be greater than the whole number if the fraction is greater than 1.

Q: How do I determine whether the product of a whole number and a fraction will be greater, less, or equal to the whole number?

A: To determine whether the product of a whole number and a fraction will be greater, less, or equal to the whole number, you need to compare the value of the fraction to 1. If the fraction is greater than 1, the product will be greater than the whole number. If the fraction is less than 1, the product will be less than the whole number. If the fraction is equal to 1, the product will be equal to the whole number.

Q: What are some examples of products of whole numbers and fractions?

A: Here are a few examples of products of whole numbers and fractions:

$7 \times \frac{5}{4} = \frac{35}{4}$
$8 \times \frac{3}{2} = \frac{24}{2} = 12$
$9 \times \frac{2}{3} = \frac{18}{3} = 6$

Q: How can I practice calculating the product of a whole number and a fraction?

A: You can practice calculating the product of a whole number and a fraction by trying out different examples and using online resources or worksheets. You can also try solving problems on your own and checking your answers with a calculator or a friend.

Q: What are some real-world applications of the product of a whole number and a fraction?

A: The product of a whole number and a fraction has many real-world applications, including:

Calculating the cost of items on sale
Determining the amount of time it will take to complete a task
Finding the area of a rectangle
Calculating the volume of a rectangular prism

Conclusion

In conclusion, the product of a whole number and a fraction is an important concept in mathematics that has many real-world applications. By understanding how to calculate the product of a whole number and a fraction, you can solve a wide range of problems and make informed decisions in your personal and professional life.
