Answer 2

To simplify the expression 4 2/5(3/11 - a) - 1 1/5, we can follow the order of operations (PEMDAS/BODMAS). Let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions: 4 2/5 = (5 * 4 + 2) / 5 = 22/5 1 1/5 = (5 * 1 + 1) / 5 = 6/5

The expression becomes: 22/5(3/11 - a) - 6/5

Step 2: Distribute the fraction 22/5 to the expression (3/11 - a): (22/5) * (3/11) - (22/5) * a - 6/5

Step 3: Perform the multiplication: (22 * 3) / (5 * 11) - (22/5) * a - 6/5

Step 4: Simplify the expression: 66/55 - (22/5) * a - 6/5

Step 5: Find a common denominator for the fractions: (66 - (22 * 11) * a - 6) / 55

Step 6: Perform the multiplication: (66 - 242a - 6) / 55

Step 7: Combine like terms: (60 - 242a) / 55

Therefore, the simplified expression is (60 - 242a) / 55.
