Calculate your expression that results in a decimal.
Press MATH.
Select >Frac (usually the first option).
Press ENTER twice.

The calculator will display the decimal as its equivalent fraction in the simplest form. Because of that, for example, if you calculate 0. 625 and then use the >Frac function, the calculator will return 5/8.

Converting Fractions to Decimals

Converting fractions back to decimals is equally straightforward. While the calculator usually displays results as decimals by default, knowing this conversion method can be useful in certain situations. Here’s how to do it:

Enter the fraction using the n/d shortcut or by using division (e.g., 1/2).
Press ENTER.

The calculator will display the decimal equivalent. If it doesn't, ensure the calculator is set to display decimals by default (check the MODE settings).

Working with Mixed Numbers

While the n/d shortcut is great for simple fractions, it doesn’t directly support mixed numbers (e., 1 1/2). But g. To enter mixed numbers, you have two main options: convert them to improper fractions or use parentheses.

Method 1: Converting to Improper Fractions

The most direct method is to convert the mixed number to an improper fraction manually before entering it into the calculator. Take this: 1 1/2 becomes 3/2. Then, use the n/d shortcut or simple division to enter this improper fraction.

Method 2: Using Parentheses

You can also use parentheses to enter mixed numbers as the sum of a whole number and a fraction. Here's one way to look at it: to enter 1 1/2, you would type 1 + (1/2). The calculator will correctly interpret this as a mixed number.

Understanding the MATH Menu

The MATH menu is your go-to place for various mathematical functions, including fraction conversions. This menu allows you to perform various operations, such as converting decimals to fractions, finding the greatest common divisor (GCD), and more.

Press MATH.
manage through the menu options using the arrow keys.
Select the desired function and press ENTER.

The MATH menu is a powerful tool for advanced calculations and fraction manipulation.
