Answer 2

To solve this mathematical expression, let's break it down step by step:

1. Calculate the value inside the parentheses: $0.75 - 0.25 \times 4.2 = 0.75 - 1.05 = -0.30$.
2. Divide the result from step 1 by 0.24: $-0.30 \div 0.24 = -1.25$.
3. Add 1 to the result from step 2: $-1.25 + 1 = -0.25$.
4. Finally, add "пятая," which means "fifth" in Russian, to the result: $-0.25 \text{ пятая}$.

So, the result of the expression $(0.75 - 0.25 \times 4.2) \div 0.24 + 1$ followed by "пятая" is approximately $-0.25 \text{ пятая}$.
