Let's break this down step by step:

Step 1: Solve the expression inside the parentheses first:

0.45 - 4/5 = 0.45 - 0.8 = -0.35

Step 2: Multiply 0.2 by the result from step 1:

0.2 * (-0.35) = -0.07

Step 3: Add 1.6 to the result from step 2:

1.6 + (-0.07) = 1.53

Therefore, the final answer is 1.53.
