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 line.

2. How to Enter Fractions on a Calculator

Most online calculators allow you to enter fractions in one of these ways:

Where:

• \( a \) — The numerator (number of parts)
• \( b \) — The denominator (total parts)
• \( \div \) — Division symbol

Explanation: The fraction bar represents division, so a/b means "a divided by b".

3. Understanding Fraction Representation

Details: Fractions can be proper (numerator < denominator), improper (numerator ≥ denominator), or mixed (whole number + proper fraction).

4. Using the Fraction Calculator

Tips: Enter any integer values for numerator and denominator (denominator cannot be zero). The calculator will show the simplified fraction and decimal equivalent.

5. Frequently Asked Questions (FAQ)

Q1: How do I enter fractions on a basic calculator?
A: Use the division key (÷) between numerator and denominator (e.g., 3 ÷ 4 for 3/4).

Q2: What if my calculator doesn't have a fraction button?
A: Convert the fraction to division (a ÷ b) or decimal form (0.75 for 3/4).

Q3: How do I simplify fractions?
A: Divide numerator and denominator by their greatest common divisor (GCD).

Q4: Can denominators be negative?
A: Technically yes, but standard form places the negative sign with the numerator.

Q5: How are fractions used in real calculations?
A: Fractions are essential in ratios, proportions, measurements, and probability calculations.
