$1\frac{3}{16}$

Answer 2

Let's break down the expression step by step:

1. (7/4)² is equal to (7/4) * (7/4) = 49/16.

2. 4.1 - (49/16) = 65/16 - 49/16 = 16/16 = 1.

Next, let's calculate the sum on the right side:

1. 16 3/5 can be converted to an improper fraction: (5 * 16 + 3)/5 = 83/5.

2. 2 1/4 can be converted to an improper fraction: (4 * 2 + 1)/4 = 9/4.

3. 9/4 multiplied by 0.5 = (9/4) * (1/2) = 9/8.

Now, we can add the two results:

1 + 9/8 = 8/8 + 9/8 = 17/8.

Therefore, the final result is 17/8.
