1. What is a Fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts. It consists of a numerator (top number) and a denominator (bottom number) separated by a fraction bar.

2. How to Enter Fractions on Different Calculators

Basic Calculators: Most basic calculators don't support direct fraction input. You'll need to divide numerator by denominator (a ÷ b =).

Scientific Calculators: Many have a dedicated fraction button (often labeled a b/c). Press this button between numerator and denominator entries.

Graphing Calculators: Typically have a fraction template in the math menu. On TI calculators, press ALPHA then Y= to access the fraction template.

3. Converting Between Fractions and Decimals

To convert a fraction to decimal: divide numerator by denominator.
Example: 3/4 = 3 ÷ 4 = 0.75

To convert decimal to fraction: use the calculator's conversion function or multiply decimal by denominators until you get an integer numerator.

4. Simplifying Fractions

A fraction is simplified when numerator and denominator have no common divisors other than 1. Find the greatest common divisor (GCD) of both numbers and divide both by it.

5. Frequently Asked Questions (FAQ)

Q1: Why can't I enter fractions directly on my calculator?
A: Basic calculators typically don't support fraction display. You'll need to perform division or upgrade to a scientific calculator.

Q2: How do I enter mixed numbers?
A: On scientific calculators, use the a b/c button. Enter whole number first, then fraction parts.

Q3: My calculator shows decimals instead of fractions - how to change?
A: Look for a button labeled F↔D (fraction/decimal) or check mode settings to change display format.

Q4: Can I perform calculations with fractions?
A: Yes, on scientific calculators you can add, subtract, multiply and divide fractions directly.

Q5: What if my denominator is zero?
A: Division by zero is undefined. The calculator will display an error.
