📚 Topic Summary
When subtracting fractions with like denominators, you only subtract the numerators (the top numbers) and keep the denominator (the bottom number) the same. Think of it like subtracting slices from a pizza that's already cut into equal pieces. For example, if you have $\frac{5}{8}$ of a pizza and eat $\frac{2}{8}$, you're left with $\frac{3}{8}$.
In mathematical terms, if you have two fractions $\frac{a}{c}$ and $\frac{b}{c}$, then $\frac{a}{c} - \frac{b}{c} = \frac{a-b}{c}$. Always remember to simplify your answer if possible!
🧠 Part A: Vocabulary

✏️ Part B: Fill in the Blanks
When subtracting fractions with ______ denominators, we only subtract the ______. The ______ stays the same. For example, $\frac{7}{10} - \frac{3}{10} = \frac{?}{10}$. Remember to ______ if possible.
🤔 Part C: Critical Thinking
Sarah ate $\frac{2}{6}$ of a cake, and John ate $\frac{1}{6}$ of the same cake. How much more cake did Sarah eat than John? Explain your answer.
