1. What is 3-Digit Fraction Calculator?

This calculator helps 3rd grade students solve word problems involving fractions with 3-digit numerators and denominators. It supports addition, subtraction, multiplication, and division of fractions.

2. How Does the Calculator Work?

The calculator performs fraction operations using standard mathematical rules:

Addition: \[ \frac{a}{b} + \frac{c}{d} = \frac{(a \times d) + (c \times b)}{b \times d} \]

Subtraction: \[ \frac{a}{b} - \frac{c}{d} = \frac{(a \times d) - (c \times b)}{b \times d} \]

Multiplication: \[ \frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d} \]

Division: \[ \frac{a}{b} \div \frac{c}{d} = \frac{a \times d}{b \times c} \]

3. Importance of Fraction Operations

Details: Understanding fractions is crucial for 3rd grade math development. It builds foundation for more advanced math concepts and real-world applications like measurements and ratios.

4. Using the Calculator

Tips: Enter 3-digit numbers (100-999) for all numerators and denominators. Select the operation type. The calculator will show the result in fraction form, simplified form, and decimal form.

5. Frequently Asked Questions (FAQ)

Q1: Why focus on 3-digit fractions?
