Answer 3

It looks like you've provided a mathematical expression with three parts. Let's break it down step by step:

1. 3,38 - 2,24: This seems to be a subtraction operation with decimal numbers: 3.38 - 2.24 = 1.14

2. 1,25: This appears to be a standalone number: 1.25

3. 28 × 3.9 × 5 / 14: This is a multiplication and division expression: (28 × 3.9 × 5) / 14 = 546 / 14 = 39

So, the result of the entire expression is:

1.14 - 1.25 + 39 ≈ 38.89
