Understanding Fractions

Definition of a Fraction

A fraction is a numerical representation of a part of a whole. It is expressed as a ratio of two numbers, where the top number represents the numerator and the bottom number represents the denominator. The numerator is the number of parts being considered, while the denominator is the total number of parts in the whole.

For example, the fraction 3/4 represents three parts out of a total of four parts. The numerator is 3, and the denominator is 4. Fractions can be used to represent quantities that are not whole numbers, such as 1/2, 2/3, or 5/8.

Types of Fractions

There are three main types of fractions: proper fractions, improper fractions, and mixed numbers.

A proper fraction is a fraction where the numerator is less than the denominator. For example, 1/2 is a proper fraction because the numerator (1) is less than the denominator (2).

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. For example, 5/3 is an improper fraction because the numerator (5) is greater than the denominator (3).

A mixed number is a combination of a whole number and a proper fraction. For example, 2 1/2 is a mixed number because it represents two whole units and one-half of a unit.

Understanding the different types of fractions is important when working with fractions on a calculator. It is also important to know how to convert between different types of fractions, as this may be necessary when performing calculations.

   • Multiply both the numerator and denominator by 10 until the decimal disappears. For example, 0.5/1 becomes 5/10.

   • Simplify the fraction if possible. For example, 5/10 simplifies to 1/2.

In conclusion, entering fractions on scientific calculators can be done easily using the fraction button or by converting decimals to fractions. By following these simple steps, users can perform complex mathematical operations involving fractions with ease.

Entering Fractions on Graphing Calculators

Graphing calculators are powerful tools that can perform complex calculations. However, entering fractions on a graphing calculator can be tricky. In this section, we will discuss how to enter fractions on popular graphing calculators.

Fraction Format Input

On most graphing calculators, you can enter fractions using the “/” symbol. For example, to enter the fraction 1/2, you would type “1/2”. Some calculators also allow you to use the “frac” button to enter fractions. For example, on the TI-84 Plus CE calculator, you can press the “alpha” key followed by the “F1” key to access the “frac” button.

It is important to note that some calculators may require you to use parentheses when entering fractions. For example, on the Casio fx-9750GII calculator, you would need to enter the fraction (1/2) instead of 1/2.

Graphing Functions Involving Fractions

For example, on the TI-84 Plus CE calculator, you can use the “n/d” function to convert a fraction to a decimal. To graph a function involving fractions, you would need to enter the function in the correct format. For example, to graph the function y = (1/2)x + 3, you would enter “y=(1/2)x+3” into the calculator.

In conclusion, entering fractions on a graphing calculator can be tricky, but with a little practice, it can become second nature. By using the fraction format input and the built-in functions on your calculator, you can easily perform calculations and graph functions involving fractions.

Common Operations with Fractions

Addition and Subtraction

Adding and subtracting fractions can be tricky, but it’s a common operation that you’ll need to know how to do. To add or subtract fractions, you need to find a common denominator. This is the same as finding a common multiple of the two denominators. Once you have a common denominator, you can add or subtract the numerators.

For example, to add 1/4 and 3/8, you need to find a common denominator. The least common multiple of 4 and 8 is 8, so you need to convert 1/4 into an equivalent fraction with a denominator of 8. To do this, you multiply both the numerator and denominator by 2, giving you 2/8. Then you can add the two fractions: 2/8 + 3/8 = 5/8.

Multiplication and Division

Multiplying and dividing fractions is easier than adding and subtracting them. To multiply fractions, you simply multiply the numerators together and multiply the denominators together. To divide fractions, you invert the second fraction (flip it upside down) and then multiply the two fractions.

For example, to multiply 2/3 by 3/4, you multiply the numerators together (2 x 3 = 6) and multiply the denominators together (3 x 4 = 12), giving you 6/12. You can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 6, giving you 1/2.

Simplifying Fractions

Simplifying fractions involves dividing both the numerator and denominator by their greatest common factor. This is the largest number that divides evenly into both the numerator and denominator. Simplifying fractions makes them easier to work with and understand.

For example, to simplify 6/12, you need to find the greatest common factor of 6 and 12, which is 6. Divide both the numerator and denominator by 6, giving you 1/2.

Remember, when working with fractions on a calculator, it’s important to enter them correctly and use the correct order of operations. Using parentheses can also help ensure that your calculations are done correctly.
