Answer 1

Держи, если нужно подробно, могу написать)

Answer 2

Считаем "устно":

3,51:27=1,17:9=0,39:3=0,13

13,1-1,72=12-0,62=11,38

11,38*3=11,4*3-0,06=34,2-0,06=34,14

11,38*5=55+1,9=56,9

11,35*0,05=0,569

34,14+0,569=34,709

34,709+0,13=34,839

Answer 3

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction.

0.351:2 + 7 + 3.05 * (13.1 - 1.72)

Step 1: Calculate the expression inside the parentheses. 13.1 - 1.72 = 11.38

Step 2: Perform the multiplication. 3.05 * 11.38 = 34.699

Step 3: Perform the division. 0.351 ÷ 2 = 0.1755

Step 4: Add all the results together. 0.1755 + 7 + 34.699 ≈ 41.8745

So, the final result of the expression is approximately 41.8745.
