Answer 3

Calculation:

To solve the given expression, let's break it down step by step:

1. Calculate 12/7.5: - 12/7.5 = 1.6 2. Calculate 7.5/12: - 7.5/12 = 0.625 3. Calculate 0.25/0.4: - 0.25/0.4 = 0.625 4. Multiply the result from step 3 by the difference between 5.1 and 3.86: - 0.625 * (5.1 - 3.86) = 0.625 * 1.24 = 0.775 Therefore, the result of the given expression is 0.775.
