The TI-84 Plus is a powerful calculator used in many math classes. One of its most useful features is the ability to work with fractions. In this article, we will walk through the steps needed to make a fraction on a TI-84 Plus.
Step 1: Entering the Numerator
To enter the numerator of your fraction, press the number key for the numerator. For example, if your fraction is 3/4, press the key for the number 3.
Step 2: Entering the Division Symbol
To enter the division symbol, press the key labeled “/” or “├╖”. This will tell the calculator that you are working with a fraction.
Step 3: Entering the Denominator
To enter the denominator of your fraction, press the key for the denominator. For example, if your fraction is 3/4, press the key for the number 4.
Step 4: Converting to Fraction Form
The TI-84 Plus automatically converts decimal values to fractions. If you have entered a decimal value instead of a fraction, the calculator will convert it to the nearest fraction form. To convert your fraction to a decimal, press the “Math” key and then select “Frac” from the menu.
Step 5: Simplifying Fractions
If you have entered a fraction that can be simplified, the TI-84 Plus will automatically simplify it for you. For example, if you enter the fraction 6/12, the calculator will simplify it to 1/2. However, if you prefer to see the unsimplified fraction, you can turn off the automatic simplification feature by pressing the “MODE” key, selecting “MATHPRINT,” and then selecting “CLASSIC.”
Step 6: Working with Fractions
Once you have entered your fraction, you can perform various operations with it. For example, to add two fractions, enter the first fraction, then press the “+” key, and then enter the second fraction. To subtract fractions, use the “-” key. To multiply fractions, use the “x” key. To divide fractions, use the “/” or “├╖” key.
Tips and Tricks
- If you are working with mixed numbers, enter the whole number part first, then press the “ALPHA” key, and then enter the numerator and denominator. For example, to enter the mixed number 1 1/2, enter “1”, then press “ALPHA”, then enter “1”, then press “/”, then enter “2”.
- The TI-84 Plus also has a feature that allows you to work with fractions in your calculations. To turn on this feature, press the “MODE” key, select “MATHPRINT,” and then select “Frac”. This will display all answers as fractions.
- If you make a mistake while entering a fraction, you can use the arrow keys to move the cursor and correct the mistake.
The TI-84 Plus is a powerful calculator that can make working with fractions much easier. By following the steps outlined in this article, you can quickly and easily enter fractions into your calculator and perform various operations with them. Whether you are a student, teacher, or professional, the TI-84 Plus is a valuable tool that can help you save time and improve your accuracy.
