Test questions for subtracting fractions with common denominators (5th grade math)

📚 Quick Study Guide

🔢 Key Concept: When subtracting fractions with common denominators, you only subtract the numerators. The denominator stays the same. 💡 Formula: $\frac{a}{c} - \frac{b}{c} = \frac{a-b}{c}$ 📝 Steps:
• 1. Make sure the fractions have the same denominator.
• 2. Subtract the numerators.
• 3. Keep the denominator the same.
• 4. Simplify the fraction, if possible.
