Answer 2

To simplify the expression (0.5a - 0.46)(0.5a - 0.4b) / 2ab, let's break it down step by step.

Step 1: Expand the parentheses: (0.5a - 0.46)(0.5a - 0.4b) = 0.5a * 0.5a + 0.5a * (-0.4b) - 0.46 * 0.5a - 0.46 * (-0.4b)

Step 2: Simplify the terms: 0.5a * 0.5a = 0.25a^2 0.5a * (-0.4b) = -0.2ab -0.46 * 0.5a = -0.23a -0.46 * (-0.4b) = 0.184b

Step 3: Combine like terms: 0.25a^2 - 0.2ab - 0.23a + 0.184b

Step 4: Simplify the fraction: (0.25a^2 - 0.2ab - 0.23a + 0.184b) / 2ab

Now, the expression is simplified to (0.25a^2 - 0.2ab - 0.23a + 0.184b) / 2ab.
