1. **State the problem:** Simplify the expression $$\frac{7}{2} + \frac{3}{4} - \frac{2}{2}$$. 2. **Find a common denominator:** The denominators are 2 and 4. The least common denominator (LCD) is 4. 3. **Rewrite each fraction with denominator 4:** $$\frac{7}{2} = \frac{7 \times 2}{2 \times 2} = \frac{14}{4}$$ $$\frac{3}{4} = \frac{3}{4}$$ $$\frac{2}{2} = \frac{2 \times 2}{2 \times 2} = \frac{4}{4}$$ 4. **Perform the addition and subtraction:** $$\frac{14}{4} + \frac{3}{4} - \frac{4}{4} = \frac{14 + 3 - 4}{4} = \frac{13}{4}$$ 5. **Final answer:** $$\frac{13}{4}$$ or as a mixed number $$3 \frac{1}{4}$$. --- 1. **State the problem:** Simplify the expression $$\frac{5}{3} - \frac{7}{3} - \frac{3}{3}$$. 2. **Since all denominators are the same (3), combine the numerators:** $$\frac{5 - 7 - 3}{3} = \frac{-5}{3}$$ 3. **Final answer:** $$-\frac{5}{3}$$ or as a mixed number $$-1 \frac{2}{3}$$.
