Answer 1

28.9

Сначала действия в скобках. Умножение идет первым.

Answer 2

Let's break down the calculation step by step:

1. $8.4 \times 0.55 + 3.28$
   = $4.62 + 3.28$
   = $7.9$

2. $7.9 \times 9.2$
   = $72.68$

3. $72.68 - 43.78$
   = $28.9$

So, $(8.4 \times 0.55 + 3.28) \times 9.2 - 43.78 = 28.9$
