Introduction to Quotient and Division of Fractions

In mathematics, the quotient is a result obtained by dividing one number by another. When dealing with fractions, division can be a bit more complex, but it follows a specific set of rules. In this article, we will explore the concept of the quotient and how to divide fractions, using a specific example to illustrate the process.

What is a Quotient?

A quotient is the result of a division operation. It is the number obtained by dividing one quantity by another. For example, if we divide 12 by 3, the quotient is 4. In mathematical notation, this can be represented as:

\frac{12}{3} = 4

Division of Fractions

When dividing fractions, we need to follow a specific set of rules. The first rule is that when dividing by a fraction, we can multiply by its reciprocal instead. The reciprocal of a fraction is obtained by swapping its numerator and denominator. For example, the reciprocal of $\frac{3}{4}$ is $\frac{4}{3}$ .

Example: Dividing Fractions

Let's consider the example given in the problem statement:

\frac{5}{4 c^2} \div \frac{15}{7 c}

To divide these fractions, we can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of $\frac{15}{7 c}$ is $\frac{7 c}{15}$ .

Multiplying Fractions

When multiplying fractions, we multiply the numerators together and the denominators together. In this case, we have:

\frac{5}{4 c^2} \times \frac{7 c}{15}

Multiplying the numerators together, we get:

5 \times 7 c = 35 c

Multiplying the denominators together, we get:

4 c^2 \times 15 = 60 c^2

Simplifying the Result

Now that we have multiplied the fractions, we can simplify the result. We can cancel out any common factors between the numerator and denominator. In this case, we can cancel out a factor of 5 from both the numerator and denominator.

\frac{35 c}{60 c^2} = \frac{7 c}{12 c^2}

Conclusion

In conclusion, the quotient of the given division of fractions is $\frac{7 c}{12 c^2}$ . This result can be obtained by multiplying the first fraction by the reciprocal of the second fraction and simplifying the result.

Final Answer

The final answer is $\boxed{\frac{7 c}{12 c^2}}$ .
