Decimal Representation of Fractions

In mathematics, decimal representation is a way to express numbers using a base-10 system, where each digit represents a power of 10. When it comes to fractions, decimal representation is a useful tool for converting them into a more familiar and manageable form. In this article, we will explore the decimal representation of fractions and how to find the reciprocal of mixed numbers.

Decimal Representation of $$\frac{126}{10}$$

To find the decimal representation of $$\frac{126}{10}$$, we need to divide the numerator (126) by the denominator (10). This can be done using long division or a calculator.

Step-by-Step Solution

Divide 126 by 10: 126 ÷ 10 = 12.6
The decimal representation of $$\frac{126}{10}$$ is 12.6

Answer Options

Based on the solution above, the correct answer is:

B. 12.6

Reciprocal of Mixed Numbers

A mixed number is a combination of a whole number and a fraction. To find the reciprocal of a mixed number, we need to follow a specific procedure.

Step-by-Step Solution

Convert the mixed number to an improper fraction: $$8 \frac{1}{6} = \frac{(8 \times 6) + 1}{6} = \frac{49}{6}$$
Find the reciprocal of the improper fraction: $$\frac{6}{49}$$

Answer Options

Based on the solution above, the correct answer is:

A. $$\frac{6}{49}$$

Understanding Reciprocals

Reciprocals are an essential concept in mathematics, and understanding how to find them is crucial for solving problems in various areas of mathematics. In this article, we will explore the concept of reciprocals and how to find them for different types of numbers.

What is a Reciprocal?

A reciprocal is a number that, when multiplied by another number, results in 1. For example, the reciprocal of 2 is $$\frac{1}{2}$$, because 2 multiplied by $$\frac{1}{2}$$ equals 1.

Finding Reciprocals

To find the reciprocal of a number, we need to follow a simple procedure:

Take the number and flip the numerator and denominator.
Simplify the resulting fraction, if possible.

Examples of Reciprocals

The reciprocal of 2 is $$\frac{1}{2}$$.
The reciprocal of $$\frac{1}{2}$$ is 2.
The reciprocal of 3 is $$\frac{1}{3}$$.
The reciprocal of $$\frac{1}{3}$$ is 3.

Reciprocals of Mixed Numbers

To find the reciprocal of a mixed number, we need to follow a specific procedure:

Convert the mixed number to an improper fraction.
Find the reciprocal of the improper fraction.

Examples of Reciprocals of Mixed Numbers

The reciprocal of $$8 \frac{1}{6}$$ is $$\frac{6}{49}$$.
The reciprocal of $$\frac{1}{8}$$ is 8.
