The correct Answer is:
To determine if the rational numbers \( \frac{7}{12} \) and \( \frac{28}{48} \) are equivalent, we can follow these steps: ### Step 1: Identify the Rational Numbers We have two rational numbers: - \( \frac{7}{12} \) - \( \frac{28}{48} \) ### Step 2: Simplify \( \frac{28}{48} \) To check if \( \frac{28}{48} \) is equivalent to \( \frac{7}{12} \), we need to simplify \( \frac{28}{48} \) to its lowest terms. ### Step 3: Find the HCF (Highest Common Factor) We need to find the HCF of the numerator (28) and the denominator (48). - The factors of 28 are: 1, 2, 4, 7, 14, 28 - The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 The common factors of 28 and 48 are 1, 2, and 4. The highest of these is 4. ### Step 4: Divide by the HCF Now, we will divide both the numerator and the denominator of \( \frac{28}{48} \) by their HCF (which is 4): \[ \frac{28 \div 4}{48 \div 4} = \frac{7}{12} \] ### Step 5: Compare the Results After simplifying \( \frac{28}{48} \), we find that it equals \( \frac{7}{12} \). ### Conclusion Since both fractions simplify to the same value, we conclude that the rational numbers \( \frac{7}{12} \) and \( \frac{28}{48} \) are equivalent. ### Final Answer Yes, \( \frac{7}{12} \) and \( \frac{28}{48} \) are equivalent rational numbers. ---
