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 (the top number) and a denominator (the bottom number) separated by a fraction bar.

2. How to Enter Fractions on a Calculator

There are two main ways to enter fractions on a calculator:

• Using the division key: Enter numerator, press ÷, then enter denominator
• Using fraction key: On scientific calculators, press the fraction button (usually a b/c), enter numerator, press down arrow, enter denominator

3. Converting Fractions to Decimals

Method: Divide the numerator by the denominator (a ÷ b). For example, 3/4 = 0.75.

4. Using the Calculator

Tips: Enter whole numbers for numerator and denominator. Denominator must be greater than zero. The calculator will show both the fraction and its decimal equivalent.

5. Frequently Asked Questions (FAQ)

Q1: What if my calculator doesn't have a fraction button?
A: You can always use the division method (numerator ÷ denominator).

Q2: How do I enter mixed numbers?
A: For mixed numbers like 2½, enter as 2 + 1/2 using the calculator's memory functions.

Q3: Why does my calculator show a decimal instead of a fraction?
A: Check your calculator's mode - some need to be set to "math" or "fraction" mode to display results as fractions.

Q4: How do I simplify fractions on a calculator?
A: Many scientific calculators have a simplify function (often labeled as SIMP or ⇨Frac).

Q5: Can I calculate with fractions directly?
A: Yes, on fraction-capable calculators you can add, subtract, multiply and divide fractions directly.
