1. What is a Fraction on TI-84?

The TI-84 calculator allows you to enter and display fractions in proper format (a/b) rather than as decimals. This is useful for mathematics where exact fractional values are preferred over decimal approximations.

2. How to Enter Fractions

There are two main ways to enter fractions:

Method 1: Using the division key

1. Press the number for numerator (a)
2. Press the ÷ (division) key
3. Press the number for denominator (b)
4. Press ENTER to display as fraction

Method 2: Using the MATH menu

1. Press MATH
2. Select option 1: ▸Frac
3. Enter numerator and denominator
4. Press ENTER to display as fraction

3. Fraction Operations

Details: The TI-84 can perform all basic operations with fractions (addition, subtraction, multiplication, division) and will display results in reduced fractional form when possible.

4. Using the Calculator

Tips:

• For mixed numbers, use addition (e.g., 1 + 1/2 for 1½)
• Press MATH then 1:▸Frac to convert decimals to fractions
• Press MATH then 2:▸Dec to convert fractions to decimals

5. Frequently Asked Questions (FAQ)

Q1: Why won't my fraction simplify?
A: Make sure you're in MATHPRINT mode (MODE → MATHPRINT) and using the fraction functions properly.

Q2: How do I enter mixed numbers?
A: Enter the whole number part, press +, then enter the fractional part (e.g., 1+1/2 for 1½).

Q3: Can I store fractions in variables?
A: Yes, fractions can be stored and recalled like any other value.

Q4: Why does my fraction show as decimal?
A: Check your mode settings or use the ▸Frac command to force fractional display.

Q5: How do I convert decimals to fractions?
A: Enter the decimal, then press MATH and select 1:▸Frac.
