Introduction

When it comes to simplifying expressions involving fractions and algebra, it's essential to have a solid understanding of the underlying concepts. In this article, we'll delve into the world of fractions and algebra, exploring the steps required to simplify the expression 1610+1819\frac{16}{10} + \frac{18}{19}. By the end of this guide, you'll be equipped with the knowledge and skills necessary to tackle even the most complex expressions.

Understanding Fractions

Fractions are a fundamental concept in mathematics, representing a part of a whole. They consist of two parts: the numerator (the top number) and the denominator (the bottom number). The numerator indicates the number of equal parts, while the denominator represents the total number of parts. For example, in the fraction 23\frac{2}{3}, the numerator is 2, and the denominator is 3.

Types of Fractions

There are several types of fractions, including:

  • Proper fractions: These are fractions where the numerator is less than the denominator, such as 12\frac{1}{2}.
  • Improper fractions: These are fractions where the numerator is greater than or equal to the denominator, such as 32\frac{3}{2}.
  • Mixed numbers: These are combinations of a whole number and a proper fraction, such as 2122\frac{1}{2}.

Simplifying Fractions

Simplifying fractions involves reducing them to their lowest terms, which means finding the greatest common divisor (GCD) of the numerator and denominator and dividing both numbers by the GCD. For example, to simplify the fraction 1218\frac{12}{18}, we find the GCD of 12 and 18, which is 6. We then divide both numbers by 6, resulting in the simplified fraction 23\frac{2}{3}.

Steps to Simplify Fractions

To simplify a fraction, follow these steps:

  1. Find the GCD: Determine the greatest common divisor of the numerator and denominator.
  2. Divide both numbers: Divide both the numerator and denominator by the GCD.
  3. Write the simplified fraction: The resulting fraction is the simplified form.

Adding Fractions with Different Denominators

When adding fractions with different denominators, we need to find a common denominator. The common denominator is the least common multiple (LCM) of the two denominators. Once we have the common denominator, we can add the fractions by adding the numerators and keeping the common denominator.

Steps to Add Fractions with Different Denominators

To add fractions with different denominators, follow these steps:

  1. Find the LCM: Determine the least common multiple of the two denominators.
  2. Write the fractions with the common denominator: Multiply the numerator and denominator of each fraction by the necessary factor to obtain the common denominator.
  3. Add the fractions: Add the numerators and keep the common denominator.
  4. Simplify the result: Simplify the resulting fraction, if possible.

Simplifying the Expression

Now that we've covered the basics of fractions and algebra, let's apply these concepts to simplify the expression 1610+1819\frac{16}{10} + \frac{18}{19}. To add these fractions, we need to find a common denominator, which is the LCM of 10 and 19.

Finding the LCM

To find the LCM of 10 and 19, we can list the multiples of each number:

  • Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, ...
  • Multiples of 19: 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, ...

The first number that appears in both lists is 190, which is the LCM of 10 and 19.

Writing the Fractions with the Common Denominator

Now that we have the common denominator, we can write the fractions with the common denominator:

1610=16×1910×19=304190\frac{16}{10} = \frac{16 \times 19}{10 \times 19} = \frac{304}{190}

1819=18×1019×10=180190\frac{18}{19} = \frac{18 \times 10}{19 \times 10} = \frac{180}{190}

Adding the Fractions

Now that we have the fractions with the common denominator, we can add them:

304190+180190=484190\frac{304}{190} + \frac{180}{190} = \frac{484}{190}

Simplifying the Result

The resulting fraction is 484190\frac{484}{190}. To simplify this fraction, we need to find the GCD of 484 and 190.

Finding the GCD

To find the GCD of 484 and 190, we can list the factors of each number:

  • Factors of 484: 1, 2, 4, 11, 22, 44, 121, 242, 484
  • Factors of 190: 1, 2, 5, 10, 19, 38, 95, 190

The greatest common factor of 484 and 190 is 2.

Dividing Both Numbers

Now that we have the GCD, we can divide both numbers by the GCD:

484190=484÷2190÷2=24295\frac{484}{190} = \frac{484 \div 2}{190 \div 2} = \frac{242}{95}

Simplifying the Final Result

The resulting fraction is 24295\frac{242}{95}. This fraction cannot be simplified further, so the final result is 24295\frac{242}{95}.
