CTET Paper I (Classes I to V) 6 Feb 2023 Solved Paper

Concept:To add fractions with different denominators, find the least common denominator and convert each fraction. Explanation:Step 1: Denominators are 7 and 2. The LCM is 14. Step 2: Convert $\frac{2}{7}$ to $\frac{4}{14}$ (multiply numerator and denominator by 2). Step 3: Convert $\frac{7}{2}$ to $\frac{49}{14}$ (multiply by 7). Step 4: Add: $\frac{4}{14} + \frac{49}{14} = \frac{53}{14}$. Step 5: Write as mixed number: $53 \div 14 = 3$ remainder $11$, so $3\frac{11}{14}$. Answer:$3\frac{11}{14}$ (Option C).
