Fun Quiz on Subtracting Fractions for Elementary Students

📚 Quick Study Guide

• 🍎 Fractions Basics: A fraction represents a part of a whole, written as $\frac{numerator}{denominator}$.
• 📝 Like Fractions: Fractions with the same denominator. To subtract like fractions, subtract the numerators and keep the denominator the same: $\frac{a}{c} - \frac{b}{c} = \frac{a-b}{c}$.
• 🧮 Unlike Fractions: Fractions with different denominators. You need to find a common denominator before subtracting.
• 💡 Finding Common Denominator: Find the Least Common Multiple (LCM) of the denominators. This becomes the new denominator.
• ➕ Converting to Equivalent Fractions: Multiply both the numerator and denominator of each fraction by a number that makes the denominator equal to the common denominator.
• ➖ Subtracting Unlike Fractions: Once the denominators are the same, subtract the numerators and keep the common denominator.
• ➗ Simplifying Fractions: Reduce the resulting fraction to its simplest form by dividing both the numerator and denominator by their Greatest Common Factor (GCF).
