1. **Problem 1: Find the missing fraction in the third triangle.** Given fractions: 1/8 (orange), 5/8 (blue), and ? (green). Since the three triangles together likely represent a whole, their fractions should sum to 1. 2. **Formula:** $$\text{Sum of parts} = 1$$ 3. **Calculation:** $$\frac{1}{8} + \frac{5}{8} + x = 1$$ 4. **Combine known fractions:** $$\frac{1}{8} + \frac{5}{8} = \frac{6}{8} = \frac{3}{4}$$ 5. **Solve for $x$:** $$x = 1 - \frac{3}{4} = \frac{4}{4} - \frac{3}{4} = \frac{1}{4}$$ 6. **Answer:** The missing fraction in the green triangle is $\frac{1}{4}$. --- 2. **Problem 2: Find the missing fraction in Gambar 2 bar graph.** Given: - Gambar 1: $\frac{3}{5}$ shaded - Gambar 2: ? (top half shaded) - Gambar 3: $\frac{3}{4}$ shaded (bottom three blocks shaded out of four) Assuming each bar graph represents a fraction of the whole bar shaded. 3. **Observation:** Gambar 2 is half shaded, so fraction is $\frac{1}{2}$. 4. **Answer:** The missing fraction in Gambar 2 is $\frac{1}{2}$. --- 3. **Problem 3: Calculate $\text{Hijau} - \text{Orange}$ and $\text{Merah} + \text{Ungu}$.** Assuming the colored shapes represent fractions or values, but no numeric values are given. Since no numeric values are provided, we cannot calculate exact values. --- **Summary:** - Missing fraction in triangle 3 (green) is $\frac{1}{4}$. - Missing fraction in Gambar 2 is $\frac{1}{2}$. - Cannot calculate Hijau - Orange and Merah + Ungu without numeric values.
