The correct Answer is:
To evaluate the difference \( \frac{8 \times 9}{11} - \frac{5 \times 5}{12} \), we can follow these steps: ### Step 1: Calculate the individual fractions First, calculate the values of the fractions: - For the first fraction: \[ \frac{8 \times 9}{11} = \frac{72}{11} \] - For the second fraction: \[ \frac{5 \times 5}{12} = \frac{25}{12} \] ### Step 2: Set up the expression Now, we can write the expression as: \[ \frac{72}{11} - \frac{25}{12} \] ### Step 3: Find the least common multiple (LCM) To subtract these fractions, we need a common denominator. The denominators are 11 and 12. The LCM of 11 and 12 is 132. ### Step 4: Convert the fractions to have a common denominator Now we convert each fraction to have the common denominator of 132: - For \( \frac{72}{11} \): \[ \frac{72}{11} = \frac{72 \times 12}{11 \times 12} = \frac{864}{132} \] - For \( \frac{25}{12} \): \[ \frac{25}{12} = \frac{25 \times 11}{12 \times 11} = \frac{275}{132} \] ### Step 5: Subtract the fractions Now we can subtract the two fractions: \[ \frac{864}{132} - \frac{275}{132} = \frac{864 - 275}{132} = \frac{589}{132} \] ### Step 6: Simplify the result Now, we check if \( \frac{589}{132} \) can be simplified. Since 589 and 132 do not have any common factors, this fraction is in its simplest form. ### Final Answer Thus, the final answer is: \[ \frac{589}{132} \] ---
