The correct Answer is:
To evaluate the difference \( 6\frac{7}{15} - 5\frac{5}{12} \), we will follow these steps: ### Step 1: Convert the mixed fractions to improper fractions. **For \( 6\frac{7}{15} \):** - Multiply the whole number (6) by the denominator (15) and add the numerator (7). - Calculation: \( 6 \times 15 + 7 = 90 + 7 = 97 \) - So, \( 6\frac{7}{15} = \frac{97}{15} \). **For \( 5\frac{5}{12} \):** - Multiply the whole number (5) by the denominator (12) and add the numerator (5). - Calculation: \( 5 \times 12 + 5 = 60 + 5 = 65 \) - So, \( 5\frac{5}{12} = \frac{65}{12} \). ### Step 2: Subtract the two improper fractions. Now we have: \[ \frac{97}{15} - \frac{65}{12} \] ### Step 3: Find a common denominator. The denominators are 15 and 12. The least common multiple (LCM) of 15 and 12 is 60. **Convert \( \frac{97}{15} \) to have a denominator of 60:** - Multiply both the numerator and denominator by 4: \[ \frac{97 \times 4}{15 \times 4} = \frac{388}{60} \] **Convert \( \frac{65}{12} \) to have a denominator of 60:** - Multiply both the numerator and denominator by 5: \[ \frac{65 \times 5}{12 \times 5} = \frac{325}{60} \] ### Step 4: Subtract the fractions. Now we can subtract: \[ \frac{388}{60} - \frac{325}{60} = \frac{388 - 325}{60} = \frac{63}{60} \] ### Step 5: Simplify the result. The fraction \( \frac{63}{60} \) can be simplified. We can convert it to a mixed number: - Divide 63 by 60: - The quotient is 1 (whole number part). - The remainder is \( 63 - 60 = 3 \). - So, \( \frac{63}{60} = 1\frac{3}{60} \). ### Step 6: Simplify \( \frac{3}{60} \). The fraction \( \frac{3}{60} \) can be simplified: - Divide both the numerator and denominator by 3: \[ \frac{3 \div 3}{60 \div 3} = \frac{1}{20} \] ### Final Answer: Thus, the final answer is: \[ 1\frac{1}{20} \]
