Answer 1

Приблизительно 25,0531914893617

Answer 2

First, we need to use the order of operations (PEMDAS) to simplify the expression:

1. Parentheses: There are no parentheses in this expression.
2. Exponents: There are no exponents in this expression.
3. Multiplication and Division: We need to perform the multiplication and division from left to right: a. 117 × 5 = 585 b. 72 × 12 = 864 c. 40 × 19 = 760 d. 864 - 760 = 104 e. 351 + 585 = 936 f. 936 ÷ 104 = 9

Therefore, (351+117×5)÷(72×12-40×19) simplifies to 9.
