2). (3,4:17+1,7:34)*4,2+8,25:3. 3). ((4,1-2,5+1,07-0,08)*0,41*5):0,41. 4). 5,11*444+(10109,88:1012-4,636:38). По действиям плз

Answer 1

2) (3.4:17 +1.7:34)*4.2+ 8.25:3 = (0.2+0.05)*4.2+2.75 = 0.25*4.2+2.75 = 1.05+2.75 = 3.8

3) ((4.1-2.5+1.07-0.08)*0.41*5):0.41 = (2.59*0.41*5):0.41 = 5.3095:0.41 = 12.95

4) 5.11*444+(10109.88:1012-4.636:38) = 2268.84+(9.99-0.122) = 2268.84+9.868 = 2278.708

Answer 2

To solve each expression, we'll follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve each expression step by step:

1. (3,4:17+1,7:34)*4,2+8,25:3

Step 1: Perform division inside parentheses: (3.4 / 17 + 1.7 / 34) * 4.2 + 8.25 / 3

Step 2: Simplify the division: (0.2 + 0.05) * 4.2 + 2.75

Step 3: Perform addition inside parentheses: 0.25 * 4.2 + 2.75

Step 4: Multiply: 1.05 + 2.75

Step 5: Perform the final addition: 3.8

Therefore, the result is 3.8.

2. ((4,1-2,5+1,07-0,08)0,415):0,41

Step 1: Perform the subtraction inside parentheses: (4.1 - 2.5 + 1.07 - 0.08) * 0.41 * 5 / 0.41

Step 2: Simplify the subtraction: (2.6) * 0.41 * 5 / 0.41

Step 3: Cancel out the 0.41 in the numerator and denominator: 2.6 * 5

Step 4: Multiply: 13

Therefore, the result is 13.

3. 5,11*444+(10109,88:1012-4,636:38)

Step 1: Perform division inside parentheses: 5.11 * 444 + (10109.88 / 1012 - 4.636 / 38)

Step 2: Simplify the division: 5.11 * 444 + (9.99 - 0.122)

Step 3: Perform the subtraction inside parentheses: 5.11 * 444 + 9.868

Step 4: Multiply: 2260.84 + 9.868

Step 5: Perform the final addition: 2270.708

Therefore, the result is approximately 2270.708.

Please note that the decimal separator used in the expressions is a comma (,), which might be different from what you are accustomed to. The results are rounded to the appropriate decimal places. If there are any other questions or clarifications needed, feel free to ask!
