## What is a fraction?

A fraction is a mathematical representation of a division between two numbers. It consists of a numerator and a denominator, separated by a horizontal line. The numerator represents the number of equal parts being considered, while the denominator represents the total number of equal parts in the whole.

Fractions are commonly used in everyday life, especially in situations where a whole is divided into smaller parts. They are used in various fields such as mathematics, science, engineering, and finance.

The TI-84 Plus calculator is a powerful tool that can simplify fractions quickly and accurately, saving time and effort in math problems involving fractions.

Numerator | Denominator | Example Fraction |
---|---|---|

3 | 8 | 3/8 |

5 | 12 | 5/12 |

2 | 5 | 2/5 |

## Why simplify a fraction?

A fraction is a mathematical expression that represents a division of two numbers. It consists of a numerator (the top number) and a denominator (the bottom number), separated by a division sign or a forward slash. Fractions are commonly used in everyday life, especially in mathematics and various other fields.

When working with fractions, it is often beneficial to simplify them. Simplifying a fraction means reducing it to its simplest form by dividing both the numerator and denominator by their greatest common divisor (GCD). This process makes the fraction easier to work with and understand.

There are several reasons why it is important to simplify fractions:

**1. Easier calculations:** Simplified fractions are easier to work with in mathematical operations such as addition, subtraction, multiplication, and division. They reduce the chances of errors and make the calculations more manageable.

**2. Clearer representation:** Simplified fractions provide a clearer representation of the relationship between the numerator and denominator. They make it easier to understand the proportion or ratio that the fraction represents.

**3. Consistent format:** Simplified fractions follow a consistent format, making it easier to compare and order fractions. It allows for better organization and analysis of data involving fractions.

**5. Standardization:** Simplifying fractions helps in standardizing mathematical expressions and calculations. It ensures that different individuals or systems arrive at the same result when working with fractions.

By using the TI-84 Plus calculator’s simplify function, you can quickly and accurately simplify fractions, saving time and reducing the chance of errors. This feature is especially useful when working with complex fractions or when simplifying multiple fractions in a calculation.

When simplifying a fraction on a TI-84 Plus calculator, it is important to understand the simplified form of the fraction. The simplified form of a fraction is the result of dividing the numerator (the top number) by the denominator (the bottom number) and reducing it to its simplest form.

For example, let’s say we have the fraction 4/8. To simplify this fraction, we divide the numerator (4) by the denominator (8), which equals 0.5. However, this is not the simplified form of the fraction.

The simplified form of 4/8 is 1/2. This is because both the numerator and denominator can be divided by 4, resulting in a simplified fraction. Dividing 4 by 4 gives us 1, and dividing 8 by 4 gives us 2.

To verify the simplified form of a fraction on the TI-84 Plus calculator, you can use the calculator’s display. The display will show the simplified fraction as 1/2, confirming that the fraction has been correctly simplified.

Numerator | Denominator | Simplified Form |
---|---|---|

4 | 8 | 1/2 |

Simplifying fractions is an important skill in math, as it allows us to work with smaller, more manageable numbers. The TI-84 Plus calculator makes this process quick and easy, saving time and reducing the chances of making errors in manual simplification.

## Step 3: Verify the result

After simplifying the fraction using the ti-84 plus calculator, it is important to verify the result to ensure its accuracy. The calculator’s display will show the simplified form of the fraction, which can be compared with the manual simplification.

To verify the result, you can perform a quick division to check if the simplified fraction is equivalent to the original fraction. Divide the numerator by the denominator of both the original and simplified fractions. If the quotient is the same, then the simplification is correct.

For example, let’s say the original fraction is 12/36. After simplifying it using the calculator, the simplified form is 1/3. To verify this result, divide 12 by 36, which equals 0.3333. Then divide 1 by 3, which also equals 0.3333. Since both quotients are the same, we can conclude that the simplification is correct.

Verifying the result is important because it allows you to double-check the calculator’s accuracy and ensure that the simplification process was done correctly. It also helps in building confidence in using the ti-84 plus calculator for math calculations involving fractions.

## Step 3: Verify the result

After simplifying a fraction on a TI-84 Plus calculator, it is important to verify the result to ensure its accuracy. The calculator’s display can be used to compare the simplified fraction with the original fraction and confirm that the simplification was done correctly.

To verify the result, follow these steps:

- Look at the calculator’s display to see the simplified fraction.
- Compare the simplified fraction with the original fraction.
- Check if the numerator and denominator of the simplified fraction are both smaller than the original fraction.

By verifying the result, you can ensure that the fraction has been simplified correctly using the calculator. This step is important in math to avoid any errors or miscalculations.

## Comparing with manual simplification

To manually simplify a fraction, you need to find the greatest common divisor (GCD) of the numerator and denominator. The GCD is the largest number that divides both the numerator and denominator without leaving a remainder. Once you find the GCD, you can divide both the numerator and denominator by it to simplify the fraction.

For example, let’s say we have the fraction 12/18. To manually simplify this fraction, we need to find the GCD of 12 and 18. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 18 are 1, 2, 3, 6, 9, and 18. The largest number that appears in both lists is 6, so the GCD of 12 and 18 is 6.

Now, we divide both the numerator and denominator by 6: 12/6 = 2 and 18/6 = 3. The simplified form of the fraction 12/18 is 2/3.

To compare this result with the calculator’s calculation, we can enter the original fraction 12/18 into the calculator and use the simplify function. If the calculator gives us the same simplified form of 2/3, then we can be confident that the calculator’s calculation is accurate.
