Question

(3,8 х 1,75 : 0,95 - 1,02): 2,3+0,4 с объяснением каждого действия.

Answer 1

Начнем со скобок:3,8*1,75:0,95-1,02=3,8:0,95*1,75-1,02=4*1,75-
1,02=7-1,02=5,98
5,98:2,3=59,8:23=2,6
2,6+0,4=3

Answer 2

Calculation of (3.8x + 1.75) / 0.95 - 1.02 divided by 2.3 plus 0.4

To solve the given expression, we'll follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to ensure the correct calculation.

1. Calculate (3.8x + 1.75): - The expression (3.8x + 1.75) involves a variable 'x' and a constant. - We'll perform this calculation first.

2. Divide the result by 0.95: - Once we have the result from step 1, we'll divide it by 0.95.

3. Subtract 1.02 from the result: - After step 2, we'll subtract 1.02 from the result obtained.

4. Divide the result by 2.3: - Next, we'll divide the result from step 3 by 2.3.

5. Add 0.4 to the final result: - Finally, we'll add 0.4 to the result obtained from step 4.

Let's proceed with the calculations.
