The correct Answer is:
To solve the problem of finding the product of the LCM and HCF of the fractions \( \frac{2}{3} \) and \( \frac{3}{5} \), we can follow these steps: ### Step 1: Understand the relationship between LCM and HCF The relationship between the LCM (Least Common Multiple) and HCF (Highest Common Factor) of two numbers \( a \) and \( b \) is given by the formula: \[ \text{LCM} \times \text{HCF} = a \times b \] In our case, \( a = \frac{2}{3} \) and \( b = \frac{3}{5} \). ### Step 2: Calculate the product of the two fractions We need to calculate: \[ a \times b = \frac{2}{3} \times \frac{3}{5} \] To multiply these fractions, we multiply the numerators and the denominators: \[ = \frac{2 \times 3}{3 \times 5} = \frac{6}{15} \] ### Step 3: Simplify the product Now, we simplify \( \frac{6}{15} \): \[ \frac{6}{15} = \frac{2}{5} \quad \text{(by dividing both numerator and denominator by 3)} \] ### Step 4: Conclusion According to the relationship between LCM and HCF: \[ \text{LCM} \times \text{HCF} = \frac{2}{5} \] Thus, the product of the LCM and HCF of \( \frac{2}{3} \) and \( \frac{3}{5} \) is \( \frac{2}{5} \). ### Final Answer The product of LCM and HCF of \( \frac{2}{3} \) and \( \frac{3}{5} \) is \( \frac{2}{5} \). ---
